I used this site here https://www.freefilefillableforms.com which is accessed from the Child Tax Credit Non-filer Sign up Tool page on the irs.gov website. Once you use this tool it blocks you from being able to file a normal tax return. Now since I didn't put an amount in the Recovery Rebate Credit box (which is the amount they owe me for the 1st and 2nd check, which is for the child.) there is no way for me to fix that now.
I think your right about an amendment, but how do i amend something that's never been filed?
