I filed my 2019 taxes last month and for some reason they're files as 2020 return how can this be fixed i haven't even received my 2020 w2's yet

You could not have filed the 2020 tax return in December or even early January since the IRS Form 1040 for tax year 2020 was not available until January 7, 2021.

Did you do this?

You complete your tax return by finishing all 3 Steps in the File section. In Step 3, to e-file your tax return, you must click on the large Orange button labeled "Transmit my returns now".

After completing the File section and e-filing your tax return you will receive two emails from TurboTax. The first email when your tax return was transmitted and the second email when the tax return has either been accepted or rejected.

If you did e-file was an email from TurboTax received verifying the transmission of the tax return?

To complete and file a 2019 tax return using TurboTax you would need to purchase, download and install on a personal computer one of the 2019 desktop editions from this website - https://turbotax.intuit.com/personal-taxes/past-years-products/

A 2019 tax return can only be printed and mailed, it cannot be e-filed.
