Thanks for reaching Community, @sdm81153.
If it's a paper check, you can delete and recreate it to correct the details. If it's a direct deposit payroll processed beyond 5 PM PST, we're unable to delete nor void it.
To learn more about creating paycheck and its process, you can check this article: Create paychecks in online payroll.
I also added this link for additional information about payroll in QuickBooks Online: Help articles. This will give you more ideas on how to organized payroll.
I’m always here if you need help.
