Hi there, @sarahpays!
You can change your employee payroll setup to run your payroll successfully. I'm here to walk you through the steps.
Once done, you can successfully run your payroll.
I've attached a screenshot below for your visual reference.
Feel free to read this article for future reference: Online Payroll - Set up or Edit an Employee.
I'll be always around here in the Community to help you if you have any other concerns.
