Can't change airdrop name

My friend was messing around with my Macbook and somehow the name that shows up on airdrop for both my Macbook and my iPhone is now a different name than I want. She admitted to the deed but doesn't remember how she managed it. I'm really at a loss; I have no idea where she would have inputed it. I've changed my device name, I've checked all my contact names and iCloud info, and I've searched all around my Macbook and iPhone settings.

Where else, other than the device name, can you change the name that shows up on airdrop?

Thank you!!
