When I was asked to enter my EIP 1 I entered the wrong amount. How and where do I enter the correct amount? I did not receive $600 for each qualifying child (2) for my EIP 2 and I think correcting the Recovery Rebate Credit Form will give me the money I am entitled to for my qualifying children.
Don't change the entries on the form itself. Enter the correct amounts of the EIP1 and EIP2 payments that you did receive in the interview. To get back to the question, type "stimulus" (without the quotes) in the Search box, then click the link that says "Jump to stimulus."
I see that you posted another question about your children not being properly entered as dependents on your tax return. You can't fix that by changing the Recovery Rebate Credit Worksheet. When you get your children entered properly the Recovery Rebate Credit will also be correct.
How old are your children? To qualify for the Child Tax Credit and the stimulus payments they have to be under 17 as of the end of 2020. If they are 17 or older at the end of 2020 they do not qualify for the child tax credit or the stimulus payments.
