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.
