You cannot attach a Line in or Bluetooth Connections to a Sonos One.
Your Options are:-
Sonos Amp, Port or Sonos Play 5 Gen 2 or Sonos Five. All these devices have an auxiliary line input. You could then plug that BT adapter into the line in port.
Once connected the Turntable sound can be played on ANY/ALL of your Sonos devices.
Another Alternative is to connect the BT to a Sonos Roam and then this can share to the rest of your Sonos devices.
For the best Sound I would us the Line Out from the Turntable (assuming it has a Phono Pre-amp built in) and connect that to the input on the Port/Amp/Play 5/Five. BT is not the best way of transmitting music.

In fact only true of Roam not Move. (Unless there has been an update I missed)
Huh. I just answered this query by the OP in another thread, with essentially the same information as @bockersjv
is it possible to use a Sonos Connect to join a Sonos One to a record player?
Assuming they’re running the same OS, yes.
