Whatever you do, do not mess around in your real 2016 tax account...to do so would irreversibly destroy your 2016 tax file.
1) Your one option to do that............you could create an entirely new account in the Online software (entirely separate UserID)......but would have to re-enter everything in the Federal section and pretend you are an OR resident....and then you couldn't print out your paperwork without paying all the software fees again...but you would see the results.

2) BUYING Desktop software is the only other option. Desktop software has always been far superior to Online. In that you can create as many test files an you want , you just save each with a different file name. Problem is that you might have to buy the extra state (Since it only comes with one free state). You can download your datafile from your online account to input as your start-point too.
Or
3) Last option is to just take your current 2016 Federal printout---go to the Oregon tax website and find their 2016 PDF downloads and work thru it manually with the OR instructions.
