After studying the Oregon Pub 17, I see that the stimulus is considered a reduction in the Federal Tax Liability subtraction on the Oregon side. It appears in the OR40, line 10 (Subtractions), the federal tax paid in 2020 less $2400 (or whatever the stimulus payment #1 was). You have to compare your Federal Tax (line 16 on 1040SR) and all Federal credits with OR40 line 10 to see what TurboTax did with the stimulus payment. Interestingly TurboTax did not include the payment #2 (perhaps because most will have received this stimulus in 2021).
