iCloud restore woes
Hello all, I've tried phone chat with Apple and I've tried the Genius Bar but I'm getting no luck. Bought an iPhone 7+ a week or so ago and during the iCloud restore I'm being asked for a password to an iTunes account I don't know, consequently it won't allow me to restore any further.
The Genius Bar suggested going through my list of apps and deleting any I don't know or even use anymore, when I asked if it's possible to delete them that way he said yes, but I can't see how. I've attached a screenshot.
iPhone 7 Plus, iOS 11.2
