Filing two state returns with different filing status

I am active duty military with Virginia as my HOR. My wife works in NC, where I was stationed, and had state taxes taken out for NC. 

Last year I paid to have a "tax pro" file my taxes and they did MFJ for federal and the NC state return. Then they filed a MFS for the VA return.

I am attempting to do the same thing this year but on my own. I know I need to prepare a MFS federal return in order to complete the MFS VA return but am not sure what information needs to be provided on there. Do I include our 2 children? Do I include mortgage interest paid and property taxes paid? I'm just not sure if I include everything that I would for  MFJ federal return, minus spouses income. Looking for guidance. Thank you.
