How to add a teleportation mechanic like ender pearls in Minecraft

I am making a 2D platformer in Unity 2020.3.23f1. I have made a shooting mechanism and have written a script to save the location of where it lands. But when I added a script to change the players position to the position where the projectile lands, I sometimes teleport below ground.

How I want the teleportation mechanic to work - If I throw it at the top surface of a tilemap, I teleport there. If I throw it at a wall, I teleport to the side of the wall. If I throw it at the ceiling, I teleport to the ceiling.

How to do this? I have been searching for an answer for days.

Here is the teleportation script (inside the player) -

 private void Update()
     {
         if (shouldTel == true)
         {
             
             transform.position = new Vector2(telPoint.transform.position.x, telPoint.transform.position.y + 1);
 
             
             shouldTel = false;
         }
     }

Here is the other teleportation script (inside the projectile)

 private void Update()
     {
         RaycastHit2D hitInfo = Physics2D.Raycast(transform.position, transform.up, distance, solidChecker);
         if (hitInfo.collider != null)
         {
             if (hitInfo.collider.CompareTag("Ground"))
             {
                 Debug.Log("Teleport");
                 tel = true;
 
                 telPoint.transform.position = transform.position;
             }
 
             else
                 tel = false;
 
             DestroyProjectile();
         }
         teleport.boolTeleport(tel);
         teleport.teleportFunc(hitInfo);
 
         transform.Translate(Vector2.right * speed * Time.deltaTime);
     }
