Unintentional sale to a minor

[chpnac]

What are the consequence of selling alcohol to a minor. it was a major accident, an honest to god mistake,I miscalculated the years between alcohol and tobaco.
I went to court and plead guilty, the charges were lowered to an infraction because of a clean history. I was fined $200 and there was no probation or jail or anything like that.

I will absolutely be open and honest about it, but can this impede with the process, and will it make the process take longer. thanks everyone
