Thanks for joining this thread, maddoglee!
Let me provide some information about PAYG Instalments in QuickBooks Online. When PAYGI is enabled in the GST settings, the PAYG Instalment Liabilities is created. And when you lodge your BAS, QuickBooks Online will automatically create a journal entry against the PAYG Instalment Liabilities account and the ATO Clearing account.
Furthermore, the journal entry from the lodged BAS offsets any entry you've made for the PAYG Instalment expense. If you wanted to zero out the PAYG Instalment Liability account, you can create a journal entry.
Also, you can check the articles below to learn more about Reporting PAYG Instalments on BAS and IAS and GST Chart of Accounts and Lodgement Journal Overview.
