Your stats say you've got an IPhone 6, if that's true, then you can't go above 12.5.5.
Go to Settings > General > About and post what model you have.
If you've got a 6, then you can update to 12.5.5. If you have a 6S as you posted, then follow the directions below.
Can you post a screenshot of the whole screen, it could reveal why you aren't able to update.
Make sure you:
• Are using a WiFi connection (not a hotspot).
• Have an active cell service
• Have your battery charged at least 50%. Better yet, keep it plugged in during the update.
• Are not using a VPN connection.
• Do not have power save mode turned on.
• Do not have a beta version installed.
• You have at least 6 gigs of storage available.
