How to send email to manager after submit timesheet

i did not see any email option to send after submitting timesheet

There are three ways I have listed below to notify anyone.

1.) You can assign this document to your manager after that they recieve an notification

After submit the timesheet on left hand side in sidebar there is an assign to option simply assign to your manager.

2.) Setup notification from the notification list.

In notification define doctype
Select alert on submit
Select Recipients (only Recipientants will reviece this notification)

Add your message and hit save button.

Create Timesheets and test

3.) Create a custom Workflow & set email templates.

There are lots of ways choose as per your need.
