I have the same issue. In my case; same employer but they legally changed name part way through the year so have issued two T4's.
"This is not a software issue..."
It is most definitely a software issue because if the CRA allows it, so should the software. It should be as simple as Turbo-Tax checking box 16/17 of all T4's before applying the logic to deny a 16a/17a value. Apparently it is not an issue in Wealth Simple though - should we all just abandoned Turbo Tax in favor of another package?
"if you have a 2nd contribution (box 16A), you should logically have a 1st contribution (box 16)"
This makes sense in theory, however, with two T4's if you've already reached the maximum contribution of $4,034.10 (for 2025) on the first one then anything remaining is "additional" including any contributions made during the time period covered by the second T4.
"we suggest you to contact CRA to see if you can combine both T4s together to have only 1 but with all the amount reflecting your 2024 year."
Who is "we"? Your post was made anonymously - do you work for TurboTax?? I suggest TurboTax fixes their product rather than advising workarounds that would require users of their software to wait on hold for hours with the CRA. I have considered "fudging" the T4's as you have suggested, however, if the data we submit doesn't match the T4's on file with the CRA it is likely to trigger an audit.
It may not matter if Netfile just sends the totals rather than the individual T4 data, but again, if this is the case then it should be a very easy fix for Turbo Tax. Bottom line - Turbo Tax should accept the T4 data exactly as entered on the actual T4's without requiring a "workaround."
