Unemployment compensation earned in Oregon is taxable by Oregon, even if you are now a resident of another state. See the following:
"Total compensation includes unemployment compensation benefits to the extent the benefits pertain to the individual's employment in Oregon. If unemployment compensation benefits are received by a nonresident for employment in Oregon and in one or more other states, the unemployment compensation benefits must be apportioned to Oregon using any method that reasonably reflects the services performed in Oregon."

The Oregon unemployment you received as an OK resident is also taxable by OK, as @Hal_Al indicated. You may claim a credit on your OK state return for the tax paid to OR on the income taxed by both states, so in effect you won't be double-taxed.
