In this line: GameObject LvlT = Instantiate(LevelTutorial);, the prefab you are instantiating is stored in a local variable (LvlT).

This variable is droped at the end of its scope: the method loadLevelT() but the instantiated gameobject still exists in the scene.

The variable should also not be available in the unloadLevelT() method. Aren’t your editor and/or Unity displaying error about it ?

If you want this to work, you should declare LvlT as a class field or property instead of a local variable so it could be accessible by all your class methods.

This could be a working version of your class:

public class LevelLoadingSys : MonoBehaviour
{

   public void loadLevelT()
   {
       LvlT = Instantiate(LevelTutorial);
       load();
   }

   //unload levels
   public void unloadLevelT()
   {
       Destroy(LvlT);
   }

   //levels
   public GameObject LevelTutorial;
   private GameObject LvlT;
}

Note that I may have miss something. Try to post your whole class the next time so we do have the full context.
