What is the penalty for leaving the scene of an accident in Georgia?

Last week I was driving a rental car and took a corner too fast. I ended up hitting a curb. the tire was blown out an I belive the front axel was broken as the car was not drivable. I called the rental cars road assistance ans waited for over an hour. It was about 98 degrees and very humid. A driver of another car stopped and asked me if I needed a ride. I took the ride home and kept calling the rental car company and described where the car was again. About two hours later I got a call from the police dept and they told me I needed to turn myself in. I told them I waited for over an hour and finally took a ride from someone. It's been almost a week and I have not heard back from the police. Considering the only damage was to the wheel of the car and there was no damage to the curb do i need a lawyer? Please only serious answers and please no judgement calls.
