A 2021 tax return can only be printed and mailed, it cannot be e-filed using TurboTax.
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.
Go to this IRS website for the mailing address, by state, for the federal tax return, with and without a payment - https://www.irs.gov/filing/where-to-file-paper-tax-returns-with-or-without-a-payment
Include with the mailed return any forms W-2 and 1099 which have taxes withheld on the form.
Consider using a tracking service from the US Post Office when mailing the tax return so that you will know that the IRS received the return.
