knockback script help

I want to make an isometric rpg and need help with my knock back script. My character just teleports somewhere for a second and then is able to move.

player script:

[SerializeField]
public float movespd = 4f;
Vector3 forward, right;
public Collider[] hitBox;
public float damage;
public float knockbackForce;
public float knockbackTime;
private float knockbackCounter;
// Use this for initialization
void Start()
{
forward = Camera.main.transform.forward;
forward.y = 0;
forward = Vector3.Normalize(forward);
//changes where the vector is facing
right = Quaternion.Euler(new Vector3(0, 90, 0)) * forward;
}
// Update is called once per frame
void Update()
{
if (knockbackCounter <= 0)
{
if (Input.GetKeyDown(KeyCode.Space))
{
WeaponAttack(hitBox[0]);
}
if (Input.GetKey(KeyCode.S) || Input.GetKey(KeyCode.W) || Input.GetKey(KeyCode.A) || Input.GetKey(KeyCode.D))
{
Move();
}
}
else
{
knockbackCounter -= Time.deltaTime;
}
}
void Move()
{
Vector3 direction = new Vector3(Input.GetAxis("horizontal key"), 0f, Input.GetAxis("vertical key"));
Vector3 rightMovement = right * movespd * Time.deltaTime * Input.GetAxis("horizontal key");
Vector3 upMovement = forward * movespd * Time.deltaTime * Input.GetAxis("vertical key");
Vector3 heading = Vector3.Normalize(rightMovement + upMovement);
transform.forward = heading;
transform.position += rightMovement;
transform.position += upMovement;
}
public void Knockback(Vector3 kncPos)
{
knockbackCounter = knockbackTime;
kncPos = new Vector3(1f, 1f, 1f);
transform.position += kncPos * knockbackForce * Time.deltaTime;
}
void WeaponAttack(Collider col)
{
string oTag = col.tag;
Collider[] cols = Physics.OverlapBox(col.bounds.center, col.bounds.extents, col.transform.rotation, LayerMask.GetMask("hitbox"));
col.tag = "Hit Box";
foreach (Collider c in cols)
{
Debug.Log(c.name);
switch (c.tag)
{
case "Hurt Box":
c.SendMessageUpwards("TakeDamage", damage);
break;
default:
Debug.Log("null");
break;
}
}
col.tag = oTag;
}

other hitbox script:

public float hurtValue;
public PlayerController p1;
// Use this for initialization
void Start () {
p1 = FindObjectOfType<PlayerController>();
}

// Update is called once per frame
void Update () {

}
private void OnTriggerEnter(Collider other) {
if (other.gameObject.tag == "Player") {
Debug.Log("hit");
Vector3 hitDirection = other.transform.position - transform.position;
hitDirection = hitDirection.normalized;
FindObjectOfType<PlayerController>().Knockback(hitDirection);
}
}
