child tax credit

My 25 year old lived with us for 10 months after graduating college in 2020 and finally landed employment in November 2021 but TurboTax is showing we don't get the $500 "other dependent credit" this year. Most likely because he has made more than the $4150 limit in the 2 months he had a job but that didn't help us any for the 10 months he was living with us unemployed. Are there exceptions for instances like this?
