Underneath the blue TurboTax logo bar you will see 5 white/grey tabs

Select the FILE tab (in the program, not above)
Select File a Return
You will then have the option to select e-file
You will also have an option of having the refund Directly Deposited into your account or a check mailed. You will see those options as you progress thru the screens.
Good luck!
