Hello moderateminneapolitan,
To help resolve the issue with your Reminders not syncing, first make sure both devices has the latest update. Apple's updates contain software that is critical to the operation of your iPhone:
Update iOS on iPhone - Apple Support
Update iPhone manually
At any time, you can check for and install software updates.
Go to Settings > General > Software Update.
The screen shows the currently installed version of iOS and whether an update is available.
To turn off automatic updates, go to Settings > General > Software Update > Automatic Updates.
Update your Apple Watch - Apple Support
If they are already updated, restart both devices.
