How do I print a full tax return, with all the supporting worksheets and schedules? All I can find to print is the return as filed with the IRS.

In the print center there is an option to include all forms and worksheets.

(If the 8606 is required then it would be in the forms filed to the IRS.)

Before filing,  You can preview the 1040 or print the whole return

How to get a copy after filing

Or here's an alternate way to print by opening the filed return back up to print at the Print Center, where you can also get the worksheets.

• Log in and at the Tax Home or in the section "Your Tax Returns & Documents" for 2019, look for a link "Add a State."
• Click on "Add a State."  (you don't really add one.  That's just to open your return back up.)
• After the return is open, click in the left menu column on TAX TOOLS, then PRINT CENTER.
• Then choose "Print, save, view this year's return."
• The next screen should offer some options:  "Just my tax returns", or "include government worksheets (optional)", or "include government and TurboTax worksheets (optional.)"
• See if one of those PDFs has what you need.

@Critter-3 Got it. Thank you very much.

@macuser_22 Thank you.

Beware.  Does not seem to work for 2021 returns after filing.

Oops I did get it to work.  You must click on the return to get the options.

Glad you were able to get it to work - thanks for the update @user345657.
