Thanks for coming back here, @Wolves 1962.
Let me be your best help in understanding this.
If you need to correct an employee payment per month, you should print out all the payslips and reports since you'll be deleting an entire pay run to ensure saving the correct Pay Dates, Employee's Name, Total Pay, Taxes, and other Deductions.
Additionally, if you need to delete a scheduled pay run that has been submitted to HMRC, create a new pay schedule and add employees with the same payroll ID. For detailed information, check out this article: Delete a pay run in QuickBooks Online Standard Payroll.
Moreover, you read this article to learn how to fix common payroll errors: Fix payroll errors in QuickBooks Online Standard Payroll.
