The error literally states: 'argument must be passed with the ref keyword`. This means you have to add ref to the argument, to mark the parameter as in/out.
For example:
Distance = Mathf.SmoothDamp(Distance, desiredDistance, ref velocityDistance, DistanceSmooth);
For your function CalculatePosition, you simply defined the wrong return type. The code inside does not return a float, it returns a Vector3, as is natural for a position.
/* Does not return a float! */
Vector3 CalculatePosition(float rotationX, float rotationY, float distance)
{
Vector3 direction = new Vector3(0, 0, -distance);
Quaternion rotation = Quaternion.Euler(rotationX, rotationY, 0);
return TargetLookAt.position + (rotation * direction);
}
