I live in NC and have a regular NC job. I also teach online classes as an Adjunct Professor for a university in Kentucky. Until 2020, they withheld KY income tax. In 2020, the KY university started withholding NC income tax instead of KY income tax. In which state did I earn the income? Do I still need to file a non-resident KY return? If I do, do I just say that all of my income was earned in NC?
