I need help in figuring out the client and spouse live in NJ and CT states - want to file federal joint but need to file married separate due taxpayer lived and worked in NJ but the spouse lived and worked in CT state.

How do I create state returns as a resident married filing separately for CT return for a spouse to show Federal Adjusted Gross Income which is joint then of course deduction to reflect her portion. 

The problem is when you do by splitting the joint to separate - their income also gets split but CT state one of those states requires to get federal AGI (not direct income). 

I appreciate the input...
