T3(SUPP) error after entering T5008 slips

Stagingtt — Sun, 22 Feb 2026 19:58:58 GMT

I am using TT2025 Canada Desktop.

I have entered 4 T5008 slips in the program and when I look at the T3(SUPP) form the number of shares sold is 100 times higher than what i entered. I have checked all 4 T5008 entries. When i put in 40 shares the T3(SUPP) form shows 4000. I don see any decimal place or anything like that. Why is this happening?

Typed too quickly. Obviously I mean the S3(SUPP) form and not T3(SUPP)

The forms are still not finalized, but there will be an update released before tomorrow's NETFILE opening, so that might contain a fix for this issue.

The number of securities isn't used in the calculation, though, at least not on the S3 (SUPP).

Thank You. I shall check back after the next update. Yes, the proceeds, cost and Cap Gain figures are correct. As long as the CRA doesn't dive deep into the number of shares and flag incorrect share prices 🙃

The problem with the S3(SUPP) form is still there after the latest TT update. The shares sold column is still 100 times higher than it should be. Yes, the proceeds, cost basis and cap gain figures are correct but after dealing with the CRA’s idiosyncrasies for over 40 years I know that any noticeable change in pattern year over year is what raises the flag with them to dig deeper. If they cross check current prices with say BCE as an example it will look as if the share price was only 36 cents instead of 36 dollars. This could cause them to request more detail about the transactions. While the actual capital gains are correct this reporting issue on the S3(SUPP) form should be corrected soon so that people can file knowing they won’t be flagged for a reassessment.

@Stagingtt The CRA has the information about the number of shares sold directly on your T5008 slips, so if they need to cross reference, they will get the information from there.

I will pass this issue onto the product development team.

Thanks for that reply. That now makes sense to me that they will get their info from the T5008 slips and not the summary.

Agree that the correct "Quantity of Securities" that is used by the CRA is taken from the information entered into the TurboTax T5008 Slip, however, the information in the TurboTax Schedule 3 Supplemental Statement is still incorrect in TurboTax.

I have all the latest updates currently released and Schedule 3 Supplemental Statement is still incorrect.

The "# of shares" in S3(SUPP) is 100 X the "Quantity of Securities" entered into the T5008 which would be correct is this field was "Lots" but this is not the correct definition of this field when transferred to the S3 (SUPP).

Should be a quick fix. Has the TurboTax Product Development Team responded?

Thanks, Steve

PC Download Version - As a follow-up to my original post, I checked TurboTax 2024 to see if this was a new bug introduced in TurboTax 2025 and this same bug is also in TurboTax 2024 (e.g. multiplying Quantity of Shares on the T5008 form by 100 when displaying the # of shares on the S3(SUPP) form).

TurboTax 2023 is correct and transfers the Quantity of Shares exactly as entered into # of shares on the S3(SUPP) TurboTax form so it looks like this bug was first introduced in TurboTax 2024.

For large numbers of trade transactions, the S3(SUPP) is useful and much easier to review/proof read the T5008 entries than scrolling 3 entries at a time within the small T5008 window within TurboTax. The T5008 slip from your Financial Institution is not very useful for final verification since the ACB is rarely accurate (for a number of reasons as acknowledged by the financial institution) and these entries won't match what is being submitted to the CRA for USD T5008 entries since multiple conversion rates are often required.

I realize the Capital Gain/Loss calculations are still correct according to the T5008 form input, however, to avoid confusion for those who do check the S3 (SUPP), it should be fixed.

@SteveM-Tax

Our product development team is working on this issue, and it should be resolved in a future update.

I have the same problem. I can fix it by dividing the number of shares sold by 100 and entering that amount, but if TurboTax fixes it, am I then going to have to go back and reenter the actual amounts? I did not have this problem last year, but I used TurboTax Premier then, whereas I am using the Standard edition this year.

@tc8679 You can go back an enter the proper amounts, though the number of shares isn't actually used in any of the calculations.

The bug in the T3(SUPP) Form that was showing 100 X the "Quantity of Shares" that were entered into the T5008 Slip has been fixed in the latest TurboTax Update. I just loaded the latest update and the T3(SUPP) now shows the correct "Quantity of Securities" that were entered into the T5008 Form.

I checked my S3(Supp) and yes it has been corrected. I am glad the TT team listens when there is enough posts about an issue. I have been using it for over 25 years (originally QuickTax). There are still a number of small bugs I could complain about but I have learned to just live with. One small example is in the warnings section near the end. It warns me that my T4A(OAS) is higher than what is allowed but the warning is incorrect. It has been like that for a couple years. Think about it. Service Canada isn't going to overpay you on your OAS except for rare clawback situations and even then, they are not likely to make a mistake. I just ignore the error because it's not enough of a bother to try to get it fixed.

I get the same "OAS over the Limit Warning" every year when entering OAS payments.

The T4(OAS) Warning is not something Turbotax can calculate accurately since the OAS payout amount will depend on what age a tax payer decided to take OAS which TurboTax will not know. Delaying the start date of OAS payments provides a higher payout above the normal amount. All TurboTax can do is give a warning if it is over the max for taking it at the normal retirement age.

Stagingtt — Sat, 21 Mar 2026 20:38:31 GMT

Fair enough. I wasn't thinking of people that may wait to collect but...

Even based on the 'standard' max amount it shouldn't throw the warning. It's almost like their coding is using an 'equal to or greater' than the standard max instead of a 'greater than' so that it would need to be at least a cent over the max to trigger the warning. It's small potatoes compared to last year's initial release 😉 and it certainly isn't going to stop me from using TT in the future.
