I entered all my 2020 return info and didn't file, I now can't find it anywhere. I was done, just needed to submit. Where can i find it?

You can no longer efile a 2020 return, but if it was finished, you can print a copy (and sign it) from the 2020 PDF file and mail a paper return to the IRS (and a state return to a state tax agency, if applicable).   It's good to mail by a method that has tracking.

On the other hand, if you need to work some more/edit on the 2020 return, and if you have already paid for it, TurboTax Support should furnish you the 2020 desktop software as a download to install on your computer, and then you can open the *.tax2020 data file that you can download.

Here's how to find your 2020 return PDF and data file:

Log in, and go to the Tax Home.  Scroll down the Tax Home page to the section "Your Tax Returns & Documents."  Expand that section and choose tax year 2020.   Then you can choose to "Download/print the PDF".

If you do that, but there's no evidence of the 2020 return in that section "Your Tax Returns & Documents", then you may have multiple accounts and signed into the wrong one.    Many people end up with multiple accounts.

You can have up to 5 accounts that use the same email address for notification purposes.  A User ID may be an email address, but it doesn't have to be.  It might be only part of an email address, or it can be anything at all.

To get a list of your User IDs, reset password, and recover account access, etc., you can use the tool at the link below.  When using the Account Recovery tool, try using your phone number first if you can still access it.   After that, if necessary, then run the tool on your email address(es) you can access.

NOTE: Before running the account recovery tool below, log out of all Intuit accounts including this user forum, or you might end up in a loop.  Then clear your browser Internet cache, close your browser, then reopen it, and go to the link below.  You may wish to copy this link so you can paste it into the new browser session.

If still no luck after running that on your phone number you can still access and email address(es) that you can access,  here's another method:

Go back to the tool again, but this time leave the data field blank, scroll down a bit, then choose the small blue link that says "Try something else", and it will look you up by SSN and other parameters.
