After you file

Do you mean you did not finish preparing your 2020 return and do not have your W-2?   You have to get the W-2 from your employer.   TurboTax does not have your W-2.

 

Some employers allow you to import the W-2 through the software, but for security reasons you still need information from the actual W-2 to import it.  You might need to phone, drop in, email and/or snail mail an old employer to make sure they know where to send your W-2.
