Switch external account to internal?

Hi all, I’m new to Amazon, and required QuickSight for my current role. I received access, but it seems like it is being tagged to an external account rather than an internal amazon account so I am being charged. How can I get this switched? The wiki page is not helpful to me.
Thanks!

Hi @Julie_Lee

This seems to be an internal/amazon question - will ping you directly in slack to help you out.

Thx
