Below IDD Audit tables will be available part of the Exception Audit database schema configured in the AdminConsole->Content Management Service.
Regarding the BAD record tables which you created in Developer tool , it depends on which connection you have selected while creating the tables in Developer tool.
Please verify in Developer tool itself by opening that PDO and its connection details.
I am aware about location of BAD tables as well but don't know the table where Human Task status is stored.
e.g. like accepted , Completed , Suspended.
Any idea on where Can I find this info.
