In the United States, if you are found not guilty of a crime, you are not given penalties like a six-month probation, community service, or a suspension of your driver's license. You were convicted of something. It might not have been the initial charge but you were convicted. Question 4 should be Yes. It might have been "guilty" or "no contest" or something else.
I would also consider answering Yes to Question 7. You were inside a jail. It might have been for a couple of hours, but you were inside a jail.
Remember to attach all of the paperwork related to the case. Someone will have to review it and make a determination.
You are so close to being done with this. Be open and honest about what happened.
