Turntable not connecting.

I have connected my turntable to my Mac(using High Sierra 10.13.6)but it’s not playing my records on Audacity, only my turntable.
I am using Audacity 2.2.2

Is it a USB turntable?
If so, ensure that you connect it before launching Audacity, then select the USB option as the recording device in the device toolbar
