"Test Login Needed" App review in Google Play

I recently uploaded a new app in the google play console to review, then I was receive an email that say:

Please provide login credentials to the support team before you submit any updated version for another review (select “Test Login Needed” and include the test login account and password details in the open box field).

I can't find the “Test Login Needed” to select it.

Can anybody tell where this option is?
