I have made several posts that show up elsewhere in the Turbotax forum. Go to the "deductions and credits" section and search for the following:
Turbotax 2023 Capital Loss Carryover Worksheet "TY-21->TY22 conversion"
Here is my summary of what I found:
"As I stated in one of my previous posts, my Turbotax 2021 desktop program did not generate a Schedule D specifically for AMT purposes, although it did generate an AMT capital loss carryover figure. I simply used the 2021 Schedule D lines 7 and 15 values for regular tax purposes to fill in the blanks in 2023 "loss carryover adjustment smart worksheet." (It wasn't quite as "smart" as advertised, since it didn't simply import the information from prior years' returns, which were also prepared using Turbotax.) Inserting these values (assuming your AMT capital losses values are the same as the regular tax values--typically true) will result in correct AMT capital loss carryovers to 2023.
This problem apparently only affects early filers in 2022 with capital loss carryover. If you dig down somewhere within the "smart" worksheet (can't recall exactly where, but I remember right-clicking on one of the values to get more information), you'll get the following explanation (which I didn't discover until after I made the earlier posts) for the "conversion" worksheet:
"There was an issue fixed in early 2023 for Alternative Minimum Tax Capital Loss Carryover from 2021 to 2022. Some of 2022 returns (filed before March 1, 2023) may have brought over inaccurate information about the 2021 AMT capital loss carryover. Based on information transferred from your 2022 return, your return has been determined that it might have been potentially impacted. Although this had no impact on your 2022 tax return, we recommend double-checking your 2021 return for this information so we can get the right amount going forward." (I filed my 2022 return in February of 2023).
