First of all the Child Tax Credit on line 28 is completely different than the Recovery Rebate Credit on line 30.
Sounds like you have 3 children? You should get 9,000 for the Child Tax Credit. If you got 1,500 for the advance then you get the remaining 7,500 on line 28 which you have. Forget about it saying just 2. You are claiming 3 now. It sounds right.
What's wrong with the 3rd Stimulus payment? How much did you get? It was 1,400 per person and came out starting in March. If you didn't get the full amount or qualify for more it will be on line 30.
