If your daughter was 19 at the end of 2022 but was not a full-time student, you cannot claim her as a dependent unless she had LESS than $4400 of income in 2022. If she had less than $4400 of income then she is still a qualifying relative and you can get the $500 credit for other dependents by claiming her. She can file her own tax return to seek a refund if tax was withheld from her pay, but she must say on her own return that she can be claimed as someone else's dependent.
