@neka256 We need a better understanding of exactly what you have done. Did you try to e-file and was your e-file rejected? Or did you get some sort of notice from the IRS about your child's Social Security number AFTER your return was rejected---was your refund reduced?
If you tried to e-file and got a rejection for the SSN, then amending is not the way to fix the problem. You do not use the amendment process to fix a rejected return. Amending is only used for a return that has been accepted and fully processed---and then you find out you need to correct something.
So if you were using the amendment process to fix a rejected return---get out of that.
I clicked on “amend” by mistake

Go to My Info and make sure your child's SSN is entered correctly there. If it is correct then try to e-file again. If it is rejected again, post back here with EXACTLY the rejection message you get.
If something else happened---post back with some details so we understand. We cannot help effectively if we do not know what went wrong. We cannot see your return or your account.
And...."tax due" does mean that you owe money to the IRS---it means you are NOT getting money back.
