I'm here to help you set up your employee's time off.
If you're using QuickBooks Online, you can do so by following these steps:
Next time you run payroll, you'll see the option to enter vacation/sick hours. This is typically done as you're running payroll, however you can edit a processed direct deposit paycheck from your most recent payroll. Any changes will be made with a payroll correction on the employee's next paycheck(s): https://community.intuit.com/articles/1436553.
If you're using QuickBooks Desktop, the following article has information on vacation and sick time off: https://community.intuit.com/articles/1436940.
Please let me know if you have any further questions. I'm always happy to lend a hand.
