my 2010 tax return

[acdevergie]

I prepared my 2020 tax return using turbo tax as I have for the last 15 years. Turbo Tax claims they don't have a record of it. Why?

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

hopefully, 2010  is a mistype. if not TT only retains returns for 6 years.
