@pillarsoftheearth @DaveF1006 , I had this same issue with TT not allowing an Oregon deduction for foreign income tax paid. In my case I figured out from the 2023 Pub OR-17 (pages 72 and 74) that this deduction is phased out based my income being too high. With Federal AGI > $145k the maximum allowed deduction for foreign tax phases down to zero. Maybe this solves your mystery, too?
