You did not trigger the bar based in the information that you provide because your were under 18 for most of the time and would have accrued only 2 weeks of unlawful presence. Moreover, you were admitted in J status which is granted for duration of stay and will not lead to unlawful presence as long as there is no formal decision that your admission for duration of stay was terminated.
