Hi all,
Unfortunately, I could not find any way to locate the .tax2023 file, so I had to go down the worst case scenario:
I recreated the data file for 2023 by using the TurboTax 2023 SW and importing data from our .tax2022 file -- basically redoing the entire 2023 return. I finally managed to make the numbers on all forms, schedules, and worksheets to match those as shown on the PDF file of our original 2023 return. It took days, not weeks as I had feared, because I skipped the parts that only affected the state return. (I have not finished the state return yet, so I will see if the state carryovers are based on the federal carryover data for the year or from its own state carryover history.)
