After you file

I did received my stimulus check for 2021($600) but didn't claim my children at the time since I didn't have proper documentation. But I did not claim the child tax credit for the same reason(proper documentation of dependents) but I did when I filed this year(2022) for last year's taxes(2021). I did claim i only got $600 though and was credited for the remaining balance of my stimulus and child credit tax. So Im guessing  that's why my federal and state return are still pending after 48hrs since I filed on 02/07/2021 correct?
