Be sure you indicated in the Personal Info section of TT that you had Other State Income and that the other state was OR.
Since you are a CA resident, your rental income from both states is taxable by CA. Your resident state can tax all your income, regardless of its source.
Your rental income from OR is also taxable by OR.
CA and OR are reverse-credit states. This means that your non-resident state of OR will give you a credit on its return for the tax you pay to CA on the OR property.
To make this work in TurboTax, when you get to your state returns, be sure to complete the home state CA return before you do the non-resident OR return. This will allow the credit to flow properly.
