In Ohio, I suspect this level of charge would NOT be transferred to adult court and it only matters what age you were at the time you committed the crime. If you are adjudicated delinquent on this (what they call being convicted in juvi) then it will be on your record. It won't be clean anymore. The court has the discretion (but not the obligation) to remove such records after two years have passed since you're off any sentence/probation given.
A lawyer would be well advised. If your family (not just you) are indigent, a public defender may be available.
You (and your parents) can also expect a demand from the Walmart's "lawyers" demanding compensation of a few hundred dollars for the damages miscreants like you cause them.
