two state

I lived in MO for 6 months and moved [retired] to CT for the rest of 2019.  All of my wages were while I lived in MO and the only income I received while in CT were from SSA checks which continued from my MO residency.  What forms should I use for each state and do I need to pay an additional $44 with my Premier TurboTax product to calculate a 2nd states taxes?
