I would hope a school counselor does not advise any student to hide an academic integrity violation. It wouldn’t matter that it’s not on their permanent record…the student was caught cheating and the HS administered a punishment. And that’s exactly what the college’s question in the OP is asking for. If OP doesn’t honestly answer the question, they run the risk that a counselor or teacher writes about it in an LoR and/or a peer/a peer’s parent reports it to colleges where OP applies (which happens every day.)
