Hello norm-anvilcontra,
Thanks for choosing QuickBooks Online and its Payroll modules for managing your business's books! These are powerful tools that give you confidence in your numbers once you have everything set up just the way you need them to be. I'm happy to guide you on figuring out what to do in this situation.
Letting you know the options and finding the best solution for you is going to depend on how and why you'd like to modify or delete the payroll runs already completed in the books. Even though it sounds like you're using QuickBooks Online Standard Payroll since Advanced Payroll won't allow you to run payroll before completing your setup, the other details are key in this situation and the options available will vary depending on what you're looking to do.
Don't worry, our support team can help. I recommend getting in touch using one of the following options in order to share all the details you need with us.
