Please help me get my Unity Ads to show real ads not test ads

Basically I upgraded to Advertisements 3.1.1 and I followed this guide here https://unityads.unity3d.com/help/unity/integration-guide-unity#rewarded-video-ads and copied and pasted the "Rewarded video ad buttons" part and put my own numbers in.
I use Advertisements, not Monetization. I think it works but I won't know until I update my game.

It took me awhile to figure out that I have to destroy/delete listeners/events and I'm still not sure if I am destroying everything I should. The code was giving out double rewards to viewers until I learned that I needed to destroy events. Right now, OnDestroy will take care of the ad listener and the onclick listener. I hope that's all I needed to do, but I'm not sure. Thanks!
