My question involves criminal law for the state of: Florida

I was filling in for my friend at a liquor store because I knew how to run the type of register, where I had to manually look for a price by going back to the shelves to see the price tag. However, I got to the busy time of day where there were a lot of customers, and I was getting stressed by the long line waiting for me, so stupidly, I was running back and forth to get the prices and didn't notice that one of the girls I sold to looked about 20 and unintentionally sold her alcohol. The police came in a little later and got my information. I should have paid more attention, and I know there are no excuses but it was my first time filling in, and I was by myself with no help during a very busy hour.

i was wondering, would it be recorded into my criminal record even after I pay a fine? I haven't gone to court yet, what are the consequences?

Thank you for any help I receive...
