When you electronically file your Federal return, your state return can be sent with the Federal return if you have properly filled out the information necessary for the state return.
Start the e-file process by clicking the option "E-file” located on the navigation bar on the left side of the page. You will be asked about your federal return first, then the state. You may then continue the e-file process to submit your return.
Your e-file is complete once you see the Congratulations screen.
If your federal return is rejected, your state return will not be sent. Please refer to "My federal return was rejected. Was my state return e-filed?" for more information.
