In 2020 my children were 19, 15, 13, 11, 8, 7, 5, 2, and newborn. I didn't expect anything for the 19 year old.
The issue is that I was given child tax credit for the 8 youngest in 2020 on my taxes but somehow they didn't give me the RR for the baby born in 2020. Clearly, her SSN etc wasn't a problem if they accepted her for the child tax credit.
