IF you are living in Illinois, then the distribution is potentially taxable in Illinois. having earned the pension in Oregon is immaterial if you weer living in Illinois in 2017.
(If you moved to Illinois during 2017...you'll have a bunch of income allocations to do when you do the part-year Illinois tax return...but that 's later, and only after every scrap of the Federal tax return entries are complete and error checked)
...your choices on that page are only "Military" or "Other Distribution"
..........since it's not Military, you only have the other choice.
