You have provided no details about your son so we cannot tell if you should be getting any sort of credits for claiming him as a dependent. Provide some information---how old was he at the end of 2020? Was he a full-time student? Did he have any income of his own? How much? Was your own income the same--or about the same -- as your 2019 income?
