@JimO2 - a few more things
<<But there is no figure within the TurboTax worksheets for Colorado that equals what they use for calculating the Michigan tax credit.>>
1) did you enter into TT that one of you resides in CO and the other in MI as of 12/31/21?
2) on the MI return, is your filing status the same as your federal return (that is a MI requirement)
3) both states begin their calculations with the federal AGI (and I presume you file joint on the federal return)
4) start with the CO return, since it begins with Federal AGI, is all YOUR income - including your investment income- subtracted from the CO return. is that occuring on Line 6?
5) the tax due CO is on line 17 of the CO form. This should represent your spouse's CO tax (since all your income was presumably subtracted on Line 6)
6) Then on the MI form, it also begins with federal AGI. is your spouse's income subtracted on line 13 of the MI form?
7) the calculated tax due MI is on line17. Is there a credit on Line 18? is that what you are asking about? THat investment income taxed in CO should create a credit on the MI side unless it was also subtracted on the CO return.
does any of that help?
