You can view all of your payments on the financial transactions page. To get to your financials page, simply click on the "Financials" link in the header and then click on the "Transactions" option.
Once on the transactions page, you'll notice a set of filters at the top of the table. You can use those to locate individual transactions, as well as specific transaction types (use the last dropdown filter to filter by transaction type).
