your address on the 1040 does not come from your W-2 but from the address you entered under My Info. Did you update it?
Your w-2 address does not indicate to any tax authority that it's your state of primary residence. It's just a mailing address. many taxpayers have multiple residences.
also there are questions about the states where you earned income and additional questions about earning income in other states.
maybe we can help if you tell us what it says or perhaps the notice contains information on how to dispute it.
on the w-2 what state, if any, is indicated in box 15. if it's illinois (IL) then you failed to update your address with your employer.
