Rental Property and Taxes

For reference: I am still active duty, my HOR is Illinois, got stationed in Texas and changed my residency to Texas, bought a house and lived there for 4 years. Last year, got sent back to illinois. my house in Texas is currently rented out for the whole year 2025.

Upon filing state tax, should I use Illinois? Cause Illinois is charging me almost $3k for the rental property in Texas.

This is confusing to me. I need y’all experiences and insights. Sorry to sound stupid.
