California and Oregon are "reverse-credit" states. That means that both states tax the income, but only the non-resident state offers a credit. (Normally the home state offers a credit for taxes paid to the non-resident state.)
This means that in TurboTax in your situation you should complete your home state (CA) return before you do your non-resident state (OR) return, which is the reverse of the usual sequence.
