Nice work, you you can skip tests on the extra breadth-first-search if it's not done. You did hit the learning goals. Take a look at my comments. I think you have some issues with space complexity. If you have questions let me know via Slack.

Actually since add_helper is recursive the space complexity will be O(log n) if the tree is balanced and O(n) if it's not due to the function call stack.

Space complexity would be O(n) if the tree is widely unbalanced, but O(log n) if it is balanced.

Since you are building an array in this example, it would be O(n)
Same for all the traversals
