While using the installed version of 2023 Turbo Tax Home & Business, it may ask the user to verify that Line 4 of 2022 Form 6251 is correct. Although 2022 Turbo Tax Home & Business saved the available records, worksheets, forms, etc., as PDFs, there may be no trace of Form 6251 in any of them. On this same page, is a blue link "What if I don't have Form 6251?", with a lot of gobbledygook, ending with "If you don't know your AMTI, most people will get the same result using your "regular" taxable income (2022 Form 1040, 10)."
However, 2022 Form 1040, Line 10 is NOT "Taxable Income" (it's "Adjustments to income from Schedule 1, line 26"). Taxable Income is Line 15 - but even then, it is not the same as the AMT. This is beyond sloppy, and irresponsible. I reported this same issue to TurboTax in 2021, while preparing 2020 taxes - but they still have not addressed it.
At a minimum, Turbo Tax should at least advise the User that they could try re-installing the older version of TurboTax (assuming they are able to and it is not still installed), go to the "Forms" screen, and enter "6251" in the search box - which may produce a completed 2022 Form 6251.
Better yet, TurboTax could just include Form 6251 in the list of "Key Calculation Sheets". Or even better than that, TurboTax could stop asking the User to provide information that TurboTax already calculated and stored the previous year.
