ATO payroll category for STP P2 - back pay reporting category

Hi all,

I am just trying to fix issues with the EOFY and STP P2 to finalise EOFY payroll.  I have noticed that a back pay recorded is allocated to the reporting category - "Allowances - Tasks". I feel it should be in "gross payments" though.  Can anyone confirm this please.

If I need to change to the "gross payments" reporting category how do I update this one employee's info submitted to the ATO to then finalise our EOFY payroll..?  

TIA
