Need to display a previously hidden sub-tab on Customer form

Hi All,

We have previously hidden the tax profile sub-tab under Order Management Super User responsibility.   We now would like to display it again.  However, I cannot find it under the sub tabs to personalize.  I do see it under AR Super User responsibility, but I don't need to personalize it there.

How can I bring it back to the Order Management Super User?

Thanks
Norma
