Typically, if you swipe down the notification panel after connecting the phone to your PC via USB, there's a USB notification icon. If you tap that notification icon, it gives you various options for how you want to connect (typically MTP, PTP, Charge Only). Sometimes, this is located elsewhere in the system settings menu, so you may have to look through there to find it.
EDIT: Never mind, I just saw the options you found in the System Settings. It looks like you have that part set up correctly.
One of the other screenshots shows a notification for a software update--have you done the update yet?
