It is too late to efile it. If you did it with TurboTax and just did not file it, you can do it on a desktop computer. You may have to purchase software if you did not pay for the state last year. You will need to pay for federal if you did not pay last year. You cannot efile the return, but will have to print it, sign it, attach any documents needed for filing and then mail it. It is always advisable to use a mail service that gives you a receipt when the form is delivered.
