Intuit can't find my 2021 tax return

I used TurboTax to file my 2020 taxes. On Sat, Mar 20, 2021, TurboTax sent me an email acknowledging the federal tax return was accepted by the IRS.

Now TurboTax says they don't have a record of my 2020 taxes.

I'm ready to file my 2021 taxes

What do I do?

Where can I see a history of my files taxes on TurboTax?

Thank you!
