The state of Michigan does not tax Social Security benefits at all. Did you enter your SSA1099 in the wrong place? Did you enter it as a 1099R by mistake? Your SSA1099 must be entered in the right place in the federal return and then the information flows to the state return. It sounds like you made a mistake on the federal return. Do you see your Social Security on lines 6a and 6b of your federal Form 1040?
