if a return was filed using a SSN that's on your return that would prevent e-filing.
The Economic Impact Payment's Non-Filers tool was not intended to be used by a taxpayer who also needed to file a tax return with the IRS for tax year 2019. If you used the tool to register for a payment, you cannot file your tax return electronically. You must complete and print a paper 2019 Form 1040 or 1040-SR tax return, write "Amended EIP Return" at the top, and mail it to the IRS. These same instructions apply if you registered for your Economic Impact Payment using the IRS Non-Filers: Enter Payment Info Here tool, tax software, or a paper tax return indicating $0 or $1 of adjusted gross income. If you have a copy of the document that registered you for the Economic Impact Payment, you can include it when you file Form 1040 or 1040-SR.
