Below is the advise from ATO for your reference:

Activity Statement errors for prefill or lodgment

We’re aware of an issue affecting some taxpayers with an active account lock, such as a compromised indicator.

When attempting to retrieve activity statement prefill information or lodge an activity statement, you may experience errors that prevent successful lodgment. These errors may indicate that mandatory fields haven’t been completed or there are no active roles for the taxpayer.

Examples include:

  • G1 (Total sales) not prefilling
  • PAYG instalment amounts not being returned or unable to be varied
  • error messages when attempting to submit the activity statement.

To lodge the activity statement, your client need to contact us so we can temporarily remove their account lock, allowing the statement to be lodged.

We’re working to resolve this issue and apologise for any inconvenience. The PLS troubleshooting page has been updated to reflect this advice.
