@brendan-pullen3 you paid state tax based on where you work and then where you live. The state where you live gives you a tax credit for any tax paid in the state where you work.
So in this case, TX does not have state income tax, so the money you earned in Jan/ Feb is taxed by the state where you live and there is no credit for the state where you work.
Complete a part year Illinois tax return and report the income earned in Jan and Feb,
