State tax filing

Its very convoluted and if 3 tax guys, couldn't explain it to me-I should DEFINETLY not expect someone online to be able to understand-----venting, as I said 40 years-no issues.

 

Bottom line, IL State wants me to prove I DIDNT live here for more than 3 months in 2021-----thanks for being abrupt and will continue to get more clarification before I post again! I have lived here since 2021.
