The definition
An entity home is the single page you designate as canonical for who your business is, usually the homepage or a dedicated about page. It carries the definitive name, address, phone, description, and the outbound links to every other property you control.
The idea is to give an engine one unambiguous place to resolve questions about you, rather than making it reconcile five partial versions.
What it needs to contain
The exact canonical name, address and phone, written identically to how they appear everywhere else. A plain description of what the business does and where. Links to the properties you own, profiles, listings, social accounts, so the engine can confirm they are yours rather than guessing.
Organization or LocalBusiness markup stating the same facts the visible page states, with SameAs pointing only at properties you actually control.
The common misunderstanding
That naming a page the entity home does something on its own. It does not. The page earns the role by being consistent with every other source, and by being the one place the others point back to.
Check it yourself
Open the page you would nominate as your entity home and read it as a machine would: is the canonical name, address and phone present as text, not only in an image or a header graphic?
Then check the outbound links. Does it point at every profile you control? If a stranger had only this page, could they verify that those accounts are yours?
