Hi there JJHH,
Since the pay item was incorrectly tagged as "Not Reportable," you'll need to update it with the correct ATO reporting category. First, go to the pay item in question and change its ATO reporting category to the correct one. After updating the reporting category, send an update event to the ATO. Make sure this update event is for the last financial year to correct the records. This should ensure that the gross salary amount is correctly reported to the ATO. Here's a link that you can check, where under FAQs are the detailed steps on how to send an update event.
Best regards,
Doreen
