Q: notes?

Have you tried signing out of your iCloud account, then sign back?  Also, have you tried toggling your Notes on/off under iCloud?

Turn off on iOS devices.

Try going to iCloud.com to see if the items are there and whether they are from the device or the computer. That should show whether the device or the computer isn't syncing. If the computer, try going to System Preferences/iCloud and stop syncing. Wait a couple of minutes, then recheck syncing. If the device, go to Settings/iCloud and do the above. You can also try signing out of iCloud and then sign in again.
