You will get a state tax credit on your OR resident state income tax return for any taxes paid to CA for income that is also taxed in OR.
You
will need to file as non-resident for CA (for your CA source income only - your
CA wages). You will also need to file a OR resident state tax return (for all
income from all sources including CA wages). You will get a state tax credit in
OR for any CA state taxes that you paid on your nonresident CA state tax
return.
You
will want to work on your non-resident CA state tax return first. You will then
take a tax credit from your non-resident CA taxes on your resident OR state tax
return. (Please note that you will only get a tax credit for your CA taxes up
to the amount of OR taxes that would have been paid if the income was earned in
OR).
You only get a state tax credit on your OR resident state tax return for CA taxes paid. You will not get a credit in CA because you are only required to report CA source income on your CA nonresident state income tax return.
Just
follow the TurboTax guide when working on your states (remembering to do your
non-resident state return first) and TurboTax will do all the calculations and
credits to your resident states return
