Look under the dash on the dr1ver's side. could be clipped to a support member under there.

There is no flasher relay. The turn signal sound you're hearing is generated by a speaker. The BCM sends a CAN message to the gauge cluster which flashes the turn signal light and activates a buzzer in response when you hit the turn signal. The BCM is also solely responsible for powering the turn signal, likely via solid state power transistors in the module.
