I used Turbotax Deluxe. The kicker refund from Oregon was calculated incorrectly and my refund was lowered by almost $1000. I checked their math and it was correct.

The Oregon kicker was supposed to be the amount on 2022 Form 40 line 22 multiplied by 44.28%. The adjusted Oregon kicker was calculated correctly in the refund adjustment letter I received from the state. Why did TurboTax calculate it wrong?
