Help filing for Registered Domestic partnership

This is my first year having to file taxes as RDP. I am in California.

I have always filed as HOH since I have children who are dependents.

Now that I have RDP I believe I can still file federal returns as HOH. Is that correct? 

My RDP is incarcerated (all of last year) and does not have any income.  I've read on other posts that I have to file two or three federal returns. Is that still true if my partner did not have any income? 

For CA state returns should I file as married/RDP joint or married/RDP separate?
