I have been filing my taxes using TurboTax Delux for decades. I had a computer crash, including my backup drive. You say I didn't file with you in 2019, but I did!! ?

Can you find my 2019 return that I definitely filed with you?

Did you use TT Online (web) or TT Desktop (CD/download) for that year?

It's common to end up with multiple accounts. First LOG OUT of whatever TurboTax account you're logged into right now. Then use this TurboTax account recovery website to get a list of user ID's for an email address. Run the tool against any email addresses you may have used

If you used the Desktop CD/Download program then the only copy is on your computer and not saved or stored online.

You can also request a transcript from the IRS
