How can I print copy (get a PDF) of return with supporting worksheets now that I've filed? It seems like the only download options are .tax file or short version pdf.

If you have filed your federal tax return and it has been accepted by the IRS -

To access your current or prior year online tax returns sign onto the TurboTax website with the User ID you used to create the account - https://myturbotax.intuit.com/

When you sign onto your online account and land on the Tax Home web page, scroll down and click on Add a state. 

This will take you back to the 2022 online tax return.

Click on Tax Tools on the left side of the online program screen.  Then click on Print Center.  Then click on Print, save or preview this year's return.  

Choose the option Include government and TurboTax worksheets

I found another way -- clicking Ammend Return takes you to a screen that asks why (pick other) then a screen that asks yes or no to continue at which time, the print center appears on the left panel as well.  You don't have to select yes or no and continue the ammended return, just click on print center and you have the opportunity to download PDF with worksheets etc.
