State tax filing

Thanks, SteamTrain ... good catch

For interest on U.S. government  obligations, after adding an entry for the interest, in the page "Tell us if any of these uncommon situations apply", there is a check box "Our state doesn't tax all of this interest"). However, it lists only 6 states, and not Oregon. This situation is definitely not uncommon, and TurboTax should change their handling for it. In the 1099-INT, box 3 is "Interest on U.S. Savings Bonds and Treasury obligations", and if that is non-zero, then they should automatically set the check-box for state exemption, for all states.

'Interest income from Treasury bills, notes and bonds - This interest is subject to federal income tax, but is exempt from all state and local income taxes'

'Interest and dividend income on obligations of the federal government which are exempt from state income taxation but not from federal income taxation shall be subtracted from federal taxable income in arriving at Oregon taxable income'
