Be aware of CA's rule about filing MFS if you file your federal return as MFJ:
If you file a joint return for federal purposes, you may file separately for California if either spouse was
one of the following:
• An active member of the United States armed forces or any auxiliary military branch during 2020.
• A nonresident for the entire year and had no income from California sources during 2020.

Also, be aware that, since TX is a community property state, your wife must include half of your income on her CA return if she files in CA as MFS.
