Unfortunately, if you accidentally submitted the non-filer form but you really need to file a 2019 tax return you will not be able to file your 2019 tax return electronically.
Also, you will need to file Form 1040X, rather than Form 1040.
The non-filer submission was intended for taxpayers who truly did not need to submit a tax return for the tax year, and as such it created a very simple tax return submitting a $0 tax return. This is true whether you originated your submission from the TurboTax site or the IRS site.
This means that you now have a tax return on file with the IRS, and to submit your true return, you will need to amend it by mail using Form 1040X.
If you used the TurboTax site to submit your return, you will be able to use your TurboTax account that you created to work through your amended return.
If you used the IRS site, using our downloaded software will provide a better amendment experience as it is easier to create the original return necessary prior to creating the amended return. You can purchase that software here: TurboTax Download Software.
