Audio Setup remove echo into Teams

When I select my USB microphone I hear my voice coming out of my computer speakers. HOw do I stop my voice coming out of my computer speakers?

My goal is to have my voice through the USB mic and my system audio to be pushed through MS Teams.

Don’t know if this will help. I have 5 cameras, and at least that many mics connected to my PC. But in Teams, I manually select a specific mic for consistency and use ManyCam for camera/video switching only.
