Thank you for your response!
Yes, indeed I will file a non resident for IL and part year resident for NC and SC.
However, I believe my employer in IL have withheld state tax. According to my W2 (for my job in IL) the "state income tax" is >>0.
Given that I have paid taxes to IL I still need to pay taxes for SC? I read online that if your income is taxable to one state (IL) and is also taxable to another state (SC) then I might be eligible for tax credit so that I do not pay the same taxes for the same income in two different states.
Thank you!
