Permissions can be controlled at both the company-wide level and for individual team members. I'll guide you on how you can activate this feature, Ivy Smith.
You can enable the permission for your team member to manage their timesheet.
- Go to My Team, and select a team member.
- Choose Permissions and tick the Manage my timesheets box.

- Click Save.
To give you more details on how you can manage your individual team member settings, check this out: Manage Team Member Setting and Permissions in QuickBooks Time.
Additionally, learn how to view timesheets to access the total hours of your team member, or view different types of hours. I've added this article for more details: Learn About QuickBooks Time Reports.
