1. Where it shows up. In Desktop, going to Banking > Make Deposits opens a Payments to Deposit window automatically if anything's waiting to be grouped. In QBO, + New > Bank Deposit shows the same list under the heading Select the payments included in this deposit, same information, no separate pop-up.
2. What lands on it. Any payment recorded through Receive Payment or a Sales Receipt without picking a specific bank account directly goes here first, instead of posting straight to a bank account.
3. What doesn't show up. A payment entered with a bank account chosen directly on the Receive Payment screen skips this list entirely, because QuickBooks already knows exactly which bank line it belongs to and has nothing left to group.
4. Selecting what belongs together. Check off the payments that physically arrived together as one real bank deposit, confirm the running total matches your actual deposit slip or bank statement line, and save.
5. Why it sometimes looks empty. If everything so far was entered with a bank account chosen directly, or everything's already been grouped into a saved deposit, there's nothing left waiting, and Desktop skips straight to the Make Deposits screen with nothing to check off.
