We are not sure what your questions are. Can you ask more specific questions with details? Did you get married in 2020? Is the IRS sending you bills each year for not reporting his self employment income? Does he get 1099MISC or 1099NEC forms for it?
Oh I see you made a new post. Is he filing a separate business return like a 1120 S or 1065 return? Then he might get a K-1 from the business return to enter into your Joint personal return.
