If you still can't find anything, please check these two places: Settings>Passwords & Accounts, do you see a strange email account listed there? If there is, tap on it and then Delete Account.

Or, if you go to Settings > General > Profiles, is there anything listed there?

Thanks and have a wonderful day.
