Why won't TurboTax allow me to print/download my 2019 tax return? I filed with TurboTax and each time I click "print/download" it won't allow me to. Why?

Exactly what happens after you click on Download/print return (PDF)?

I just downloaded a PDF of a 2019 return from my TurboTax online account.

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

Scroll down to the section Your tax returns & documents.  Click on the Year and Click on Download/print return (PDF)

If you used the desktop CD/Download editions installed on your computer, the only copy of your tax data file and any PDF's will be on the computer where the return was created.  TurboTax does not store online any returns completed using the desktop editions.
