The Total Discounts and Balance Usage block is designed to lead towards what your payment gateway will pay out. Orders settled with the customer's digital balance, in cash or by check are real sales, but that money does not flow through Stripe (or your other gateway), so their amounts are listed here as reductions alongside coupons, refunds and cancellations. Each line also shows a Total Unpaid tooltip for orders of that method that are still unpaid. Payment methods that are not enabled on your account and have no amount are hidden.
