Why when initiating targetRotation variable we did not specify it as private?

The previous variables like moveVertical or movement have been declared as private, how is targetRotation different?

Because targetRotation is declared inside a method or block (an enclosed set of curly braces) its scope, or where in can be accessed, would already restricted to that method or block. So all variables inside a method are considered local and don't need an access modifier like private.

public class PlayerMovement : MonoBehaviour {
    private float turningSpeed = 20f; //...available to any method in the class

    void FixedUpdate () {
        if (movement != Vector3.zero) {
            Quaternion targetRotation = Quaternion.LookRotation(movement, Vector3.up);
                // ... can access targetRotation anywhere inside here
        }  
        // but can't access it outside of the if block.
    }  // end method
}  // end class
