Hi Paula3
Generally speaking, there are 3 ways to consider: reverse the original pay then re-record the pay; record an adjustment pay; include the adjustment in the next pay run.
If you want to record an adjustment, please first of all find out what the correct amount should be, in order to work out if any payments, hours, superannuation or tax needs to be adjusted. For more details of which option to choose and how to record, please do check out this Help article: Changing a recorded pay.
Please feel free to let us know how you go, and if you have any further questions.
