My dad enrolled me in school under my REAL NAME, my birth name. All my documents for DACA are under my real name. My concern is, did I enter with inspection?

Technically, I was inspected. I came to the US through Dulles Airport. I was inspected, but no fingerprints or anything like that. But it was under a different last name. As soon as I came here, my dad changed my last name to his last name and enrolled me in school. He used my REAL birth certificate, foreign passport (which has my real name) and enrolled me in school. So the person I came here as, under a fake name, pretty much disappeared. Does that make sense?
