One final Update 🙂 It again talked with FTB, this time via chat, here is the answer I got:
"1/2 the community income which consists of wages earned during the marriage, would be reported. If that applies. But from what you stated it seems you were not married while she may have had California sourced income or was a California resident. If that is the case, there would be no community income. she would just file the 540NR as Married Filing Separate (MFS), with her own income."
This also confirms what you were also saying, thanks a lot Terri for the help.
