How do I undo a non filer return to file my 2019 return? IRS website prompted me to input my bank account information using the "non filers" section for stimulus return.

You can’t. Since you told the IRS you will not file a tax return this year, they will not allow you to e-file a tax return as a security precaution. You need to print your return and mail it.

@Opus 17 Can you confirm that the filer does not need to amend their tax return but can just prepare, print and mail a return without amending it? That is how I've been answering but some others are saying the return must be amended.

I don’t know exactly what the non-filer document is that is being sent to the IRS so I don’t know whether it has the force of a tax return and must be amended or not.
