Thank you for this! By the definitions on the helpful TurboTax help page you reference above, we confirmed that my college-student daughter is a resident of our home state, Virginia, and a non-resident of Illinois, her university state (but is still required to file in Illinois, since she earned more than their exemption amount)(and also in Virginia, though she owed nothing). However, as we complete her state TurboTax forms (everyone: start with the remote/college state, to better populate your home state!), the TT step-by-step did not make it possible for us to declare this. Since her W2 showed income in her college state, the TT step-by-step said, "We can tell you were a part-year resident of Illinois in 2022 from your federal taxes", and did not give us the option to change that assumption. I had to override the step-by-step and go straight to the form to specify that she was a non-resident rather than a part-year resident.
