Please follow these steps:
a) Go to QuickBooks >> Employee Tab >> Employee Center. Select the employee and go to Edit Employee screen.
b) In there you have Change Tabs. Select "Payroll and Compensation Info". From there you would see the option "Use time data to create paychecks". If you want this option to be checked then you can select it and hit "Ok" to go out of this screen and if you don't want this option to be selected then you would need to first check this and hit "ok" and then come back again to uncheck this.
c) Once you have done that, you can go back to TimeRewards and download your hours without any problems.
