My iPhone is still waiting for approval from my Mac. How can I assure I am properly signed in to iCloud on my Mac?

My iPhone7 is still waiting for approval (15 minutes at least) from my Mac to approve my iPhone 7 for Two-Factor Authentication for Apple ID. How can I assure I am properly signed in to iCloud on my Mac?

I am at home with my own wifi connection.

MacBook Pro (Retina, 13-inch, Mid 2014) OS X El Capitan, version 10.11.6
