Hi @MaryK4, after some more digging around, I think I understand what I'm supposed to do. Since I wasn't paying NY taxes while living in IL, I would file my part-year resident return for IL as normal. However, since I was double taxed after moving to NY, I would file a part-year resident return for NY and take the other state tax credit for my NY state return (my resident state) and not IL.
Can you please verify if my understanding is correct? Thanks for all your help with this.
