Follow these steps to review and add them to your books:
Open the Bookkeeping menu and hit Transactions.
Click on App transactions, then the For Review tab.
For each transaction, choose an action, depending on the status:
Add or Match: This transaction is ready to add to your books. If QuickBooks is connected to the bank account you use to deposit Square payments, you can match it to a specific transaction that’s already in your books. Note: To make sure all your sales data from Square are added to QuickBooks, we suggest you add transactions from the App transactions area and then match them from the Banking menu.
Review: There are multiple transactions in the books that could be the same as the transaction from Square. Confirm which transaction it matches.
Once added, you can review them by navigating to the Reviewed tab, then choose the sales receipt or deposit under the Added/Matched section.
