Hi Leanne-G,
It's interesting how the PAYG period for your report shows July instead of June. Generally, reporting periods are set while registering with the ATO based on the turnover of your business. I recommend reaching out to ATO to make sure all of this is correct. Additionally, you can make sure that the pay items are correctly set in the BAS, then you can compare the payroll activity report for that quarter to the values shown in the GST return report.
If after following those steps mentioned the report still does not show the correct values, I recommend creating a support ticket from the My Account page for further help.
Thanks,
