Yes I need to know what account I sent my tax return to

Since you cannot file a 2020 tax return at this time, you must be referring to a prior tax year.

Look at the Federal Filing Instructions page in the PDF of your tax return.  It will have how you selected to receive the tax refund.  If you selected direct deposit the bank routing and account number will be on the page.

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 bottom of the screen and on the section Your tax returns & documents click on Show.  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.
