Hello Chikichiki187, 

Thank you for reaching out to the community. Here are some instructions to delete timesheets:

1. In QBO, at the top, select the + icon, then Approve Time.

2. Navigate to the correct date range and then select an employee's name to expand their timesheet details.

3. Select any timesheet row to display the timesheet details.

4. At the bottom, select Delete.

Please have a go and let us know how you went. If you have further questions, please feel free to reply here and I can help! 

Cheers,

Bowie
