The debt account tiles on the classic version of the Dashboard page have a button labeled "Quick Pay". This is just a fast way to record a payment versus going into the Debt Details page and doing a manual transaction. When doing a Quick Pay transaction, the payment amount and payment date are what is used on the transaction. You don't have to use the pre-populated information, you can change the date and amount as needed.
Note that on the current version of the Dashboard page, the button is just labeled "Pay", but it does the same thing.
