Hi, you can shut down SageMaker Studio resources per the documentation here - https://docs.aws.amazon.com/sagemaker/latest/dg/notebooks-run-and-manage-shut-down.html (you've linked to Studio Lab documentation, so making sure). In addition, I see you've been charged for hosting and you've since deleted the endpoints, and don't see the hosting charges after deleting them.
For data wrangler, once you have the flow saved, you need to shut down the app (closing the window does not automatically shut down the app). Note that if you open the DW flow later, it does start a compute instance, which you'll then have to shut down.
If you've deleted the user profile (and associated apps), you shouldn't be seeing any more Studio charges for that user profile. If you still see the DW charges (and there's no other user profile), please cut a ticket to support for further investigation.
