After you file

Ok i understand. I also read that they can't touch the Stimulus and Child Income Tax Credit. For example early in the year (2021) when i received the 3rd and last stimulus payment i didn't claim my children (2) but i will be receiving the remaining balance for that as well as i didn't claim the Child Tax Credit early in the year at all but did at the end when I filed for taxes. I read that they can't and won't touch those funds? Is that true? For example my return to says its 12k plus 3k state but out of that(15k in total) 9k is owed stimulus and child income tax credit.
