Did you ever get to the bottom of your issue - that is, why it happened??
I discovered when doing the 2024 taxes for my husband and myself that if you income split, TurboTax automatically moves some of your income tax paid credit to the other person as well. That is, I transferred income to my husband, and TurboTax proceeded to reduce my taxes paid credit and increase his by the same amount. Then of course neither return matches up with the T slips, so it is red-flagged at CRA for re-assessment.
TurboTax has known of this problem for at least 2 years and has failed to fix it. Oh - and you cannot override this action, if you can even figure out what happened...I say that because the "help" person I talked to at length did not have a clue and suggested that I call the CRA. When I pointed out it was a problem in TurboTax, not CRA, she hung up on me. With help from another post on here, I did figure it out, to the penny.
Anyway, if you income split with your wife, that may be the source of the problem.
