After you file

More income = more tax.    So it is entirely possible that you owe now that you added a W-2 to show that you had more 2020 income than you originally entered on your tax return, especially if you did not have enough tax withheld from that income.  

 

Sorry---you do not get to be so literal about "when" you received a stimulus payment.   If you received the 1st or 2nd EIP payment it does not matter when you received it---you have to say that you got it.  The IRS will cross check anyway and see that you got the payment so even if you answer incorrectly, they will find out you got it and you will still owe.   Many tax returns have ended up in the error department when people have answered incorrectly about stimulus money they received----and it delays processing by months and months.
