If your Form 1099-G Unemployment did not have Boxes 10a, 10b or 11, it means that they did not withhold state taxes. In the Unemployment (1099-G) interview, you should be able to leave these boxes blank.
If the program is requiring entries and will not let you continue without them, you can select your state (Iowa or IA) for 10a, any number for 10b (e.g. 99-9999999), and "$0" for Box 11.
