That's helpful. But a more specific question then:
I worked for a company in 2020 working in Illinois. I then moved to Texas, and only received a severance as a lump sum one-time payment by the former employer in 2023, 3 years later, while residing in TX. Turbotax asks me when filing the IL taxes: "How much of the $XXX [2023 income] did you earn while working in Illinois?".
My answer intuitively is $0, because I did not earn any of that 2023 income in Illinois, as I did not live there.
Do you agree that I should put $0, or should I put the severance pay here?
Obviously, in TX I would not pay any state taxes, so the prior example of a credit between two states is not really a factor. Thank you in advance.
