I'm Getting Two Sound Signals When I Record from My USB Turntable

I was going through the usual Win 11 BS where it wants to call my USB turntable a Microphone and make its signal mono. I was trying to record a stereo record using Audacity, as I’ve done in the past with success, but it had reverted to mono–even though in Preferences in Audacity it’s set as 2-channel stereo.
I must have really screwed things up in my computer’s sound settings. I now get an echo effect: the turntable plays straight through to my system, but when I record, I get two sound signals: the direct input from the turntable and the recording being done by Audacity.
The upside: I can now record in stereo again, and when the recordings are played back without the turntable’s interference, they sound fine. So my guess is that I somehow enabled direct playthrough from my USB turntable to my computer’s sound system.
I can’t figure out how to disable this direct play-through and would like to. There are times when it would be nice to be able to listen to vinyl through my computer system–but not while I’m trying to record something in Audacity!
I would imagine this is an easy fix, but the solution eludes me at present, and Google is useless, now that AI offers incorrect “help” at every turn.
I hope my dilemma is coherent and that someone can help me get back on track. Thank you for reading this.

Uncheck “Listen to this device” …

I found that setting and unchecked the listen to this device box. Thank you.
turning the system sound volume off for the turntable playback also works. Things appear to be back to normal and I can record in stereo–for the time being.
