The following is my understanding based on other posts on this site. If there are errors in it please point them out.
In the USA there is a distinction between overstaying and unlawful presence. Most but not all overstays also entail unlawful presence. In particular as a minor you overstayed but did not accrue unlawful presence. This is important because automatic bans from the USA are based on unlawful presence. So you probably don't have a ban from the USA.
OTOH your visa is almost certainly void despite appearing valid. The USA voids visas for people who overstay, even minors.
So you should apply for a new visa. You should be honest about your overstay in your application. If you get caught lying then your chances of ever entering the USA again will be very low.

How a Visa Overstay Affects a Minor
When a minor overstays a nonimmigrant visa, even if for only a few weeks, he or she can expect, just like all other visa holders must, that the visa will be automatically voided.
Therefore you must get a new visa.
