How to add a new legal entity to eBus Tax?

Hello,

We already have eBus Tax setup for two legal entities/ledgers in the US.  The tax regime code is "US SALES TAX".  We've been using this tax setup for over 3 years without any problems.

I recently created a new legal entity, ledger, and operating unit (call it ZPSH) that will function in the US tax system.  I've forgotten how to "connect" this new legal entity/ledger, ZPSH, to the existing US tax regime.

In reviewing Tax Configuration > Tax Regimes > Update Tax Regime, it appears I should add the new legal entity in this navigation.  Do anyone in the eBus Tax community know if this is the only place I need to update?  Is there any other changes needed?   Thank you.
