After you file

Let me ask you, did you file using your paystub and your W2 is different?  That's a big reason we tell people to wait to get their forms.  Your W2 usually does not match your last paycheck.  

 

There's no advantage to filing early.  Even if Turbo Tax lets you submit your return they will just hold all the returns until the IRS opens filing on Feb 12, 2021.  So there is no hurry.  And a lot of people who file early find out they have to amend later like when they get their actual W2 and 1099 forms.  Or they get more forms than they were expecting.
