To track sick and vacation pay and balances,
First, set up the balances and the accrual methods on the employee records.
Then, set up and use sick and vacation pay items (as you set up an hourly or salary item you can pick the type of item it is, whether regular pay or sick or vacation.)
If you have only one category of paid time off, PTO, then usually this is tracked as vacation and you can change the label that is used on pay stubs to PTO or similar in payroll preferences.
