After you file

Thanks for your responses! So I looked through my transcript for 2021 and I do see a $1,400 "recovery rebate credit", however I can confirm that I have not received this rebate credit, if this is considered the third stimulus. The communication did not mention payments for child tax credit, if I had not received the rebate credit, how would I go about it? If I did not receive the rebate credit, can I open a case to get my refund adjusted to where it was originally approved for? What would my next steps be?
