Character Rotation

So I have this code to make the player look forward while moving along the vertical axis.

 if (Input.GetAxis ("Vertical") > 0 | Input.GetAxis ("Vertical") < 0) {
     
                 Quaternion turnAngleFB = Quaternion.Euler(0, centerPoint.eulerAngles.y, 0);
     
                 character.rotation = Quaternion.Slerp(character.rotation, turnAngleFB, Time.deltaTime * rotationSpeed);
     
             }

        

What I'm trying to do is achieve the same effect on the horizontal axis, where the front face of the player faces in the direction its moving along the horizontal axis. This is what I have so far, but I'm missing something and I'm almost certain its something super simple that I'm not getting...

     if (Input.GetAxis("Horizontal") > 0 | Input.GetAxis("Horizontal") < 0) {

         Quaternion turnAngleLR = Quaternion.Euler(0, centerPoint.eulerAngles.y, 0);

         character.rotation = Quaternion.Slerp(character.rotation, turnAngleLR, Time.deltaTime * rotationSpeed);

     } 

Any help? Thanks in advance!
