if the prompt asks for it, you have to answer yes. Write down your explanation in the box, and then this transgression ill be ignored.
Most of us were young and stupid once too.
@Goro Thanks for the reply! I will make sure to include that on all my secondary prompts!
I would never question Goro, but unless a prompt specifically says something like,
"Please list any infractions that occurred when you where an adult or minor.", DO NOT list it.
No one can legally access your juvenile record.* (I would even take issue with the example question above being asked, since again, your juvenile record is not public record to anyone other than law enforcement, the court system, and your parents.)
*There are exceptions in a handful of states, that require you to divulge an incident if for example it were something you could've been charged with as an adult, in that state. There are also other exceptions, so see last sentence.
I understand that in your case, you listed it on your primary application, so you've already put it out there. Explain the situation in its entirety and be done with it. But in the future...no, no, and no. You'll only be shooting yourself in the foot.

But seriously though, I've been "involved" in the whole legal/criminal/records/expungements/pardons/BS game for about 10 years because of my own stupid mistakes.
You really need to check with your specific state (and/or the licensing board of the state in which your envision yourself going to school/practicing in) and see what their laws are.
Those of us who were ignorant in our youth and now have records, understandably have to go the extra 30 miles and do the legwork when it comes to researching stuff like this.
