Married File Jointly for CA and deduct dividend&interest under spouse's name (outside of CA)

So I started working and living in CA since 6M ago, and my spouse is in another state (never stayed in CA).

1. When MFJ in TurtoTax for CA state tax, can we deduct dividends&interests in my spouse' accounts from AGI? It seems currently TurtoTax is just adding everything indiscriminantly. But theoretically all these are not earned in CA but are still taxed.

2. Is there option to file MFJ on federal but MFS (separately) for CA? It seems not to be an option under normal circumstances (we are not military, for example)
