In order to e-file your return, simply log into your TurboTax account (or set up a new account by going to https://turbotax.intuit.com/:(
1) Select the version of TurboTax that is right for you
2) Complete your returns through the very end of process
3) Choose FILE RETURNS
Remember, your state returns will come up as well for you to complete (if state allows e-file; if not, you will be given the option to print the returns and mail in)
It really is as simple.
To check your returns, just go back through your return and verify all is correct:
