If you used TT to prepare and e-file those returns then the pdf you saved will include your electronic filing page which you can print.
And....no one has filed a 2020 return. The tax returns everyone has just been filing are for 2019--the tax year that ended on December 31, 2019. You will not file a 2020 return until next year.
Do you know how to access your accounts?
Many people have multiple TT accounts and forget how to access them. Log out of the account you are in now.
Or did you use the desktop version of TurboTax? If so, the files are on your own hard drive or any backup device you used like a flash drive.
