Indiana residency question if married to nonresident alien treating as a resident for tax purposes.

I am a full year resident of Indiana, but my non resident alien lived in Indiana for a few months in 2019. We are electing to treat my nonresident spouse as a resident for tax purposes, but it is confusing if this only applies to federal taxes and not state taxes.

 

The software allows to change residency from full year to full year, part year, nonresident, or reciprocal nonresident. These options drastically change the tax refund.

 

I am having trouble finding information about what my spouse would be considered. Thanks
