A panel appears when an entity has enough notability and consistent, verifiable facts across the sources Google trusts. You cannot fill out a form to create one; it is algorithmic. Once it exists, a verified representative can claim it and suggest changes, which are reviewed against public sources.
A wrong panel usually means Google merged you with a confused or better-known entity. The fix is upstream: clarify your entity home, align your profiles, and let Google recrawl and reconcile.
