Thanks for bringing this situation in the Community, stylemaster1,
Let me get the help you need in Lodging Activity Statements.
To further isolate the issue, I'd recommend logging into ATO Portal and check the settings if it matches what's in QuickBooks Online.

I'd appreciate if you'd update me on how it goes, I'm always here to offer additional help.
