Player moves to camera Z position when not told

So as i was working on my camera code i came across a rather big issue. While i finally figured out how to move the camera to the players Y position smoothly, it happened to also place the player’s Z position to the camera’s Z position. This is completely unintentional and i can’t for the life of me figure out why this is happening as i can’t see where i instruct the player to move to the camera. Long story short: anybody got any idea how to fix this? (little tip: don’t stop coding for a month…)

CODE:

using UnityEngine;
using System.Collections;

public class cameraMovement : MonoBehaviour {

	// Use this for initialization
    
    public Transform playerTransform;
    public Transform cameraTransform;
    public Transform moveToTransform;
    public Vector3 tempCalcVectorX;
    public Vector3 tempCalcVectorY;
    public float newCameraYPos;
    public float cameraYPos;
    public float tempCameraYPos;
    public float curHeightOffset;
    public float maxHeightOffset;
    public float moveToSpeed;

    void Awake () {
        moveToTransform = GameObject.Find("player").transform;
        cameraTransform = transform;
        playerTransform = GameObject.Find("player").transform;

	}
	
	// Update is called once per frame
	void Update () {
        newCameraYPos = playerTransform.transform.position.y;
        cameraYPos = transform.position.y;
        
        curHeightOffset = newCameraYPos - cameraYPos;

        if (curHeightOffset <= maxHeightOffset) {

            moveCameraToPlayer();

        }

        tempCalcVectorX = new Vector3(playerTransform.transform.position.x, 0, 0);
        tempCalcVectorY = new Vector3(0, playerTransform.position.y, -10);

        moveToTransform.position = tempCalcVectorY;

	}

    void moveCameraToPlayer() {
    
        float step = moveToSpeed * Time.deltaTime;
        transform.position = Vector3.MoveTowards(moveToTransform.position, transform.position, step);
    
    }

}

Transform is a Class and therefore a reference, not a value variable.

You take a reference to players transform

moveToTransform = GameObject.Find("player").transform;

Then in update you change the transforms position.z to -10 (which is the default Camera z)

tempCalcVectorY = new Vector3(0, playerTransform.position.y, -10);
// this is the player transform and yoou are modifying player's position
moveToTransform.position = tempCalcVectorY;
