It's so hard to teach my autistic son anything because he screams over me. He is 13 and he is getting worse with doing this not better?

Any tips?
Update: He screams that I am annoying him when I try to tell him anything and he screams he already knows everything.
Update 2: I mean I'm only talking about teaching him to put his rubbish in the trash and not around the house and wash a knife after using it stuff like that but he just screams.
