I was also hit by this same bug in TT. What I learned from this issue is before you start your taxes for the new year, run the prior year's TT, update the software, open the last year's file, save it and only then import the new saved file. A few years ago, 2021 if I recall, there was a bug that did not populate the depreciation correctly for entry to the following year, so the same thing happened to me. They fixed the bug after I submitted my return, but I never updated my TT for the prior year. That is why you should update the prior year TT and run the prior year file before you import it. (try to find that hint anywhere!) You need to amend the prior years. You can only amend the last 3 years and get a refund. Start with the first year (oldest one) that is wrong and amend that. Then use that info in the first amended year and amend the next year until you get to the current year. I sent those in and waited a bit for them to be received before I sent in the current year's return using the prior year's amended return. Good luck! I ended up amending 3 years of federal and 3 years of state returns. It was a rather painful lesson.
