See: https://www.mythtv.org/wiki/DVR_Service#DeleteRecording

You can use curl again. If the <RecordedId> is in available, it's easier.
Otherwise, you need ChanId and StartTime. Something like:

   curl --data RecordedId=fromYourDump yourBackendIPorHostname:6544/Dvr/DeleteRecording

I assume KQD is one of the "other channels" you cleaned up in a previous
post.
