Hi there CHARYCEM,
When reconciling a BAS payment, we allocate them to the ATO Clearing account. If you've lodged your BAS in QuickBooks Online, a journal entry will be created and moves the GST Liabilities Payable amount to the ATO Clearing account. And then match the BAS payment on your Banking/Transactions page.
You can check these articles to learn more about how to record and match a GST payment in QuickBooks:
Feel free to let us know if you have more questions. Have a nice day!
