State tax filing

@TomD8 
I have completed the Federal MFJ return.  Next need to work on VA 760PY for my husband, filing status #3 - Married, filling separate returns.  In order to get his AGI, I am creating a mock Federal MFS - husband's.  However, since he is domiciled in VA, do I need to add half of my income (from CA) to his mock Federal MFS to get his AGI?

For VA 760PY, could you please confirm if followings are correct?

1) His VAGI includes only his W2 from VA, all his interest / dividend regardless location of the banks, stocks gain / loss (exercised after moving to VA), and 50% of the rental income from CA property. 
2) He doesn't need to report 50% of my income (1099-NEC, Interest / Dividends) from CA. 
3) Because I am the nonresident in VA and no income from VA source, I don't need to file VA form 763.

Thank you!
