I am also using the web version of Turbo tax 2023 and had this same issue. I was struggling to reprint the historical tax returns which consisted of the Governmental and TurboTax forms.
What I had to do was go to the Tax Home > Your tax returns & documents > click on 2021 > amend (change) 2021 return > amend using turbo tax oneline.
Now once you get into this page, it asks you why you are amending, ignore all that and click on the left side:
Click on tax tools > print center > print, save or preview this years return. Once in this next page you can print with all the more detailed forms.
Please note, I STILL couldn't find the worksheet, so I just went to the Schedule D AMT form with the header "Capital Gains and Losses as Refigured for the Alternative Minimum Tax". In this form I was able to find the fields the program was asking for.
