I'm in the same scenario with 2 kids claim CTC but not the 3 kid that was born in 2021. You said to check line 28 in form 1040, mine is blank. In theory 2 kids above 6 should get 3000 x2 minus 1,500 x2 + 3600 should equal 5100 but I'm receiving less than that. I triple check the dependent's information, no they didn't work, live with us the whole year. Let me know what I'm doing wrong, thanks.
