State tax filing

Oregon (OR) requires tax to be paid only on the income derived from OR sources.  When you finish the income section of the OR return, first you will see the screen titled 'Here's the income that Oregon handles differently' where you will select  'Done with income'.

Next you will each the screen titled 'Oregon Source Income and Adjustments', where you can enter only the income that should be taxed to OR.
