What does this mean?

The account "TNT Checking nnnnnnn" was not synced.
Parameter cpData.aggregator[0].cpid must be specified for this request.

Where do I find that parameter and what should I set it to?

That Reset Sync should have gotten rid of all sync errors by creating and uploading a new file to the Sync server.

If you haven't done so already, I'd say it's time to call Quicken Support on the phone and request help.  Let them do a screen share session with you to review the situation on your computer, to determine the nature of the problem and to figure out how to fix it.

Where does this message popup? While working with Quicken on your desktop / laptop or while working with the Quicken on the Web app or the smartphone app?

Please try to Reset Sync so that the current cloud sync file is replaced with a fresh complete copy
Do note that a full Sync process may take many minutes to complete.

Log out of your mobile app, then do this on your desktop / laptop:

How to reset Sync to Cloud

1. Go to Edit / Preferences / Quicken ID, Sync & Alerts
2. Under the "Mobile and Web" group to the right, if present, click the "Reset your cloud data" link and follow the instructions until it is complete.

I did. Thank you. I have two checking accounts on Quicken. The first is Bank of America which Reset quite nicely following your instructions. The second is Northern Trust which returned the attached error panel.

The Northern Trust account has recurring update problems. When I attempt a One Step Update, I get this (attached) panel. There is a workaround where I enter a dummy password 'Quicken1' twice, hold down Shift/CTRL and press ENTER. This works except when it doesn't. It takes the Northern Trust Help Desk and "Lon" from Intuit to fix it.
