We'd love to help you complete your tax return, but need more information. Can you please clarify your question?
Are you a student? Or in the military? Please explain why you think you may be an Illinois resident even if you never lived or worked there in 2020.
State residency is based on many factors. Some people think there are a resident of whatever state they have a driver's license or voter's registration card from. That's often not true.
You are probably a resident of the state you work in, since that is where you presumably live and work, even if you haven't taken any steps to become a resident, but we would need more information.
