Hi there, eatennant.
The maximum number of hours field in QuickBooks Desktop is available to all employees, regardless if they are new or not. Let's download a payroll update, then go back to the employee's setup to enter the limit for sick accrual.
To download an update, please go to the Employees menu and scroll down to Get Payroll Updates. Then, click Update.
You can also contact our Payroll Support Team in case you can't still see the field in the existing employee's setup. Here's how:
Let me know if you have follow-up questions. I'd be glad to help you again.
