I cant seem to figure out where to add the 'self.slots.sort()' method.

I don't get why I can't simply add in the 'self.slots.sort()' line right after 'super().add_items(items)' line.

inventory.py 
class Inventory:
    def __init__(self):
        self.slots = []

    def add_item(self, item):
        self.slots.append(item)

class SortedInventory(Inventory):
    def add_item(self, item):
        self.slots.append(item)
        super().add_item(item)
        self.slots.sort()

Since your override calls the base class method, it doesn't need to "append" the item itself. That causes the item to be added twice, which then makes the final result different from what the challenge is expecting.
