Approval of first in-App purchase

I am looking for some insight and an assist (planning to test in-app purchase with TestFlight) - all works in Xcode. I have created my very first in-App purchases App (I have other paid apps in App store) Under Distribution tab in the Monetization section i created the in-app purchases item. I completed all fields and the status is now changed from waiting fior metadata to ready to submit.. Per my readings the in-app purchase item would be reviewed with a new version of the App. I uploaded a new version, added sandbox tester and submitted it for review.. My App in TestFlight now shows status of Testing, but the in-App purchase still shows waiting for review.

On the Distribution tab the "Add for Review" button is active but it seems a bit illogical for me to click it as the in-App purchases is the only completed item on my App's distribution tab (I am not ready to submit for review yet..) So as illogical as it appears, is this the way to get your first in-App purchase approved?
