Michigan Property Tax C

I have a question regarding form 5049 for Michigan.  I have a situation where a couple married in October of 2020 but they lived together the whole year.  The husband owned the house and the wife had no legal claim to it.  When I enter the wife's income the fact that they lived together before marriage do I have to include all of her income on column B of form 5049 or do I only enter the prorated amount from October since she was not married before to husband and had no legal right to the house.
