Filing Michigan state return with Federal. Are the AGI and refund fields for the Michigan signature federal values or state values?

I'm trying to electronically file a federal, wisconsin, and Michigan returns through TurboTax. The signature for Michigan requests last year's AGI and refund/tax due. However, there is no indication if this is to come from the federal return or the Michigan return. Anyone know which should be entered? If Michigan and I didn't have to file in Michigan last year, do I just enter $0 in both?
