You should enter each spouse's residency information separately in the Personal Information of TT.
For the part-year resident spouse, their State of Residence is their state of residence as of December 31st of the tax year. Then indicate that they also lived in the other state, and enter the date they began living in the current state.
If the part-year resident spouse had no income other from outside one of their resident states, then answer NO to having had "other state income."
