MFJ Federal & MFS in Community Property State

I'm active duty, California resident, and my wife is civilian, Texas resident. We both live and work in Texas. She doesn't require a state tax return for Texas because of no income tax. Am I able to just file joint for my California return, or does her working in her state of residence prevent me from doing that?

 

My confusion is that when I go to file separately I now have to add in all the community property adjustments, which halves my California return because now part of my withheld taxes are registering as hers. Which would then mean I would have to file a California tax return for her. Or do I not put state taxes in that portion of the adjustment?
