Im trying to add timesheets from last week but it's telling me that the day has been approved. No timesheets have been approved yet.

Hi office287,

Welcome to Community!  Having the ability to approve employee timesheets is essential before proceeding with QuickBooks Online Payroll.  I'd be glad to point you in the right direction so you can accomplish your QuickBooks goals as soon as possible!

You can approve or unapprove hours for one employee or multiple employees by following this helpful guide.  If you require additional assistance, please don't hesitate to reach out to QuickBooks Time support.

Feel free to reach back out if you have any other questions.  We'd be happy to help!
