I have a return with a carryforward adoption credit, however, ProConnect is giving me an e-file critical diagnostic because one of the adopted children is now 18. The credit was from 2020 when the child was eligible. The child being 18 now has no bearing on the eligibility of the carryforward being used. Looks like this error was also in ProSeries too, but the user fix there was deleting the birth year out, which doesn't seem like that will be the work around in ProConnect.
