How do I add a payment processor?

How do I add a payment processor? Every time I click on "ADD NEW PAYMENT PROCESSOR," the training video pops up.

The training video is to show you how to set up your Authorize.net before adding it to the software. If you are good with the setup of your Authorize.net account, you can click on the do not show check box at the bottom of the video to proceed with adding your payment processor.
