Thanks a lot, I will follow the links and see what I will be able to get from them.
It is very tricky but I would your original recommendation will still apply. We have in fact 6 weeks of "community property" in 2017 but she was not living in CA those 6 weeks (she was already moved here to WA), so how can it be counted as a CP adjustment in CA since the income was acquired while neither of us was in CA.
I also refer also to this statement in 540NR instructions "If the spouse earning the CA source income is domiciled in a community property state, community income will be split equally between spouses". So the spouse earning CA source income was not domiciled in WA. She was domiciled in WA after the CA source income has stopped.
