Instantiating UI element at mouse position on click

Everything works fine except for the position of the element. The position is WAY off where I click. In fact, it's about 100 times X & Y pos; I know that because I literally tried dividing the position by 100 and it at least put it on my screen, but still offset from where the cursor was.

 static public int points; //Total game points
 
     public Vector3 mousePos; //To store mouse position
 
     public Transform incrementElement; //The UI element I'm instantiating
     public Transform parentObj; //The UI Canvas
     
     public void Points(int increment) //Called OnClick()
     {
         mousePos = Camera.main.WorldToScreenPoint(Input.mousePosition); //Gets mouse position
         points += increment; //increases points variable by increment
         var NewIncrementElement = Instantiate(incrementElement, 
                                           transform.position, 
                                           Quaternion.identity) 
                                           as RectTransform; //instantiates the UI element
         NewIncrementElement.anchoredPosition = (mousePos); //moves element to mouse position. 
                                                         //I tried instantiating at mousePos too
         NewIncrementElement.SetParent(parentObj); //sets the element to be a child
                                                 // of the Canvas, this is necessary, right?
     }

I thought maybe it had something to do with the fact that the camera is tiny and the canvas is colossal, but when I zoom out to see my element, even the Canvas is small on screen. My scene is centered around 0,0,0, and the element is at 34k. I'm working with 2D, BTW, that's probably relevant here.

Note: I'm making a clicker, like Cookie Clicker. I want a little +1 to appear when I click. That's what I'm trying to do here. If there's a better way you can think of, let me know. I imagined it would be possible to just draw text, without the use of another object, but I couldn't find anything.
