Same issue as the other guy, no 10a or 10b or 11, obviously the state is Iowa so that answers 10a and there is a box with the state taxes withheld amount though it’s not numbers as box 11 but rather labeled as just “Iowa income tax withheld” but that still leaves the question of 10b. The number you gave is the federal tax ID for IDR (state equivalent of IRS) not the state ID for unemployment which is what box 10b is supposed to be
