Fictional Element in Essay

I recently got into college but I have had something nagging on my conscience. On my college app, I said my grandfather told me a “quote” about his sister when I was nine when it was really my dad who told me when I was around 11. What do I do? Should I confess? Perpsective from people with experience in admissions would be appreciated.

It is not that big a deal, stop worrying.

You have absolutely nothing to worry about. Put it out of your mind.

Do not worry. It’s a tiny little thing.

Any former admissions people’s perspective?
