Nebraska is one of a handful of states with a "convenience of the employer rule" regarding remote work performed by a non-resident. Here is Nebraska's law:
"If the nonresident's service is performed without Nebraska for his or her convenience, but the service is directly related to a business, trade, or profession carried on within Nebraska and except for the nonresident's convenience, the service could have been performed within Nebraska, the compensation for such services shall be Nebraska source income."

If that law applies in your case, then your remote income is taxable by NE. It is also taxable by MI, because your resident state can tax all your income regardless of its source.
You'll be able to claim a credit on your MI return for the taxes paid to NE on the dollars taxed by both states, so in effect you won't be double-taxed.
In TurboTax, be sure to complete the non-resident state return before the home state return, so that the program can calculate and apply the credit.
