We have qualified for the JobKeeper subsidy for the month of April. However STP was submitted for both pay runs in April already without any of the required new payroll items such JOBKEEPER-TOPUP / JOBKEEPER-START-FNXX.
Amend your last pay to include the JobKeeper transactions and then run the STP file again. Make sure that you choose "full file replacement" - see top left immediately below the "pay date". It is quite intuitive once you are in to GovConnect
