I am unable to download my completed return as a pdf file. The link on the main page only downloads as a html file with a watermark "do not file, form not final."

Try this alternate method.

Here's how you can get your most up-to-date PDF with the worksheets, summary pages, etc.  You can open your return interview and go to the Print Center, where you can choose from various PDFs.

NOTE:  When you open your return back up, do not make any changes in it if it's already been filed.  If you later have to amend the return, it has to start off exactly as it was when it was originally filed.

• Log in and at the Tax Home or in the section "Your Tax Returns & Documents" for 2024, 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 interview 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.)"
•  The latter has the most pages.

NOTE:  Remember all PDF tax documents and tax data files are very sensitive files, since they contain your personal ID info, financial data, and possibly bank account numbers, etc.  Be sure to store them safely and securely to guard against computer theft, hacking, etc.
