Can I find proof of filling 2021 Federal Taxes on Turbo Tax?

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/

Start the 2024 online tax return by entering some personal information then click on Tax Home on the left side of the screen.

On the Tax Home webpage -

Scroll down to the bottom of the screen and on the section Your tax returns & documents.  Click on the Year 2021

The status of your federal and state 2021 tax returns will be shown in the boxes on the left.  If the status is Accepted then your tax return was e-filed and accepted by the IRS or the State.  Any other status and the tax return was not filed using TurboTax.

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.
