How to determine IL portion of income

I moved to KY fall of 2020 (so resident of KY all of 2021). I was still getting a paycheck from my employer in IL for part of 2021. My employer was taking out both IL and KY state tax. Turbo Tax is asking what portion of the income on my W-2 is from IL. Since I didn't live in IL at all in 2021 should any of the income actually be considered from IL? Should I enter "0" in the question that asks "how much of the w-2 income did you earn while working in IL"? I am basically just trying to get back the state tax that was taken out for IL. They shouldn't have taken anything out because of reciprocity?
