How do I correct a tax return, when rejected by Internal Revenue?

What are you really trying to do?   Changing a 2019 return is not going to get you a stimulus check now.   You can file a 2020 tax return and use the recovery rebate credit to get the stimulus money you did not yet receive if that is why you are worried about the 2019 return.   

And a 2019 return cannot be e-filed anyhow.   So forget about 2019 if you had no income for 2019.

The stimulus check is an advance on a credit you can receive on your 2020 tax return.  If something went wrong or you did not get the stimulus check in 2020, you can get it when you file your 2020 return in early 2021

The Recovery Rebate Credit will be found in the FEDERAL REVIEW section. ( you should see "Let's make sure you got the right stimulus amount”)  If you are eligible it will end up on line 30 of your 2020 Form 1040.

Make sure that you enter ALL of the stimulus money received for the 1st and 2nd stimulus for yourself, your spouse and your children.
