Underage consumption ticket please help?

i received a underage consumption charge and was wonder if i could fight this! Im 20 years old . i was at a gas station in ohio. one of my friends was drinking and he wanted me to throw away his beer. so i took it and was gonna throw it away but there was to many people around so i just put it in my car. well i left and when i got home i got out of my car locked it forgot bout the beer and started walking in side then i noticed that two cars pulled in my drive way and i seen flashing lights. it was two unmarked cops. so i came back out and they said they were giving me a underage consumption charge. what should i do . is there any way to fight this?
