Hi tmmfs,
Could you provide us some more information on the problem you are experiencing? If you are set up for Single Touch Payroll, payment summaries are no longer generated. Instead, you'll use a Finalisation Event to complete your end-of-year processing and advise the ATO you have finished reporting wages for the employees in the financial year. Then the employees access their income statements (previously payment summaries) by logging in to their MyGov account.
If your employees were considered closely held and/or you were exempt from STP reporting, please see this guide for publishing payment summaries. The guide will take you through a checklist to ensure everything is correctly recorded prior to generating the summaries and includes FAQs for various situations that you may find relevant. Feel free to reply with some more details on the specific issue you are encountering if you have further questions as I'm here to help.
