Be aware of these Hawaii tax rules:
"A nonresident must file an Individual Income Tax Return—Nonresident and Part-Year Resident (Form N-15), if required to do so. A nonresident will be taxed on income from Hawaii sources only. A nonresident married to a Hawaii resident may choose to file a joint return with the resident spouse on Form N-11; however, the nonresident will then be taxed on all income from all sources."
See "Nonresident" on page 5 of this reference:

And from California:
"If you filed a joint tax return and either you or your spouse/RDP was a nonresident for 2020, file Form 540NR, California Nonresident or Part-Year Resident Income Tax Return."
