It depends on whether you live in WA or OR (or somewhere else). If you live in OR, then your W-2 is correct. It is all OR income, for tax purposes. Residents pay state tax on all their income, no matter where it was earned.
If you are a WA resident, ideally you get a corrected W-2. Lacking that, you use a workaround in TurboTax (TT).
At the w-2 screen modify the entries. Leave OR in box 15 but change box 16 to the amount you think it should be; leave the OR withholding in box 17.
I'm not specifically familiar with the OR software. For some states, you will reach an income allocation screen to show how much state income you had (although usually this is for all other income, rather than wages. Wages are usually allocated at the W-2 screen).
