Phone will not back up to iTunes says "iTunes could not bak up the iPhone because backup has been disabled for this phone by an administrator" I saw an earlier question that said to look for General > Settings > Device Management, this phone was never an employers and does not have Device Management.
iPhone 6s, iOS 12
Do you have a company or work email account on this phone? See this discussion: https://discussions.apple.com/thread/7691338?answerId=30739715022#30739715022
If you're sure you do not have any profile in Settings>General>Profiles, contact Apple Support directly and explain your problem, using this link:--> Get Support
