you're doing something wrong.
you are a part-year resident of Ca and should be filing form 540-NR and schedule Ca to allocate your income. here's Ca rules (Wa does not have an income tax)
California taxes all income received while you resided in California and the income you received from
California sources while a nonresident.
If you file Form 540NR, use Schedule CA (540NR) column A through column D to
compute your total adjusted gross income as if you were a resident of California
for the entire year. Use column E to compute all items of total adjusted gross
income you received while a resident of California and those you received from
California sources while a nonresident.
