Icemaker Water Supply Line Shut Off Valve
Found It! It was located under the dinette seating. I have a U-shaped dinette and after taking the cushions and board completely off the back section, the valve can be seen in the back corner under the kitchen counter near the wall. This is as bad as finding the low point drain valves under the shower pan. Not easy access for us older folks.
Thanks to everyone who offered suggestions and I hope this helps others with a 33sw.
