Do you mean you prepared a 2020 return but did not file it? It is now too late to e-file. E-filing is closed. The only way to file a 2020 return is to print it, sign it in ink and mail it in.
You have to access your own account and/or print it for yourself using exactly the same account and user ID that you used when you prepared the return.

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.
