In the Personal Info section of TT, your wife should enter MI as her State of Residence, and that she also lived in NY. The date should be the date she began living in MI. This will prompt the program to produce a part-year resident tax return for NY, on which she will report all her NY income. Since all her income was earned before her move to MI, none of it is taxable by MI. All of it is taxable by NY.
