on the federal, file Joint. 96% of married couples file Joint (and not Separate). All the tax laws that Congress passes protects the sanctity of marriage, so unless you have student debt and an income repayment plan (and still taht may not matter), filing Joint is the way to go.
for the states, your question is complex, just follow TT for the state in question. Only the income earned in that state by the respective spouse will be taxed by that state. So even if you are required to file joint in MI, that doesn't mean that the GA income is going to be taxed in MI.
Any version of TT will work; Deluxe should be all you need.
Think simply and trust TT will figure this out!
