If you ever need to know which transfer a payment was included in, you can:
First, head to the "Billing" tab
Next, click to open the details of that payment by clicking the drop-down symbol
Then, look for "Settlement Status" and "Settlement ID"
You can head to your "Company Activity Report" to view the Settlement ID that includes this payment.
**Note: Outbound Transfers may include multiple payments and refunds that are rolled together over a two-day period**
