Selling alcohol to a minor.

I am a 20 year old college student and I was given the following ticket when I was working in a gas station in Texas yesterday. I have not been given any further notice. The police said that they would call my number if they file an arrest warrant and I have to turn myself in. They also said that there might not be an arrest warrant, since I am a college student and they don’t want to give any trouble to that. They said to give the other paper to my boss and he will have to submit the following tabc papers or the gas station would be fined. I don’t know what would my further steps be. I would like to get some advice regarding this.
