Starting in March of 2012, you'll also have the option to sign up for text messages regarding your e-file status. This new feature will be phased in over a period of several weeks, and will be available to all customers on March 22.
You'll get a text message once your return is accepted or rejected by the IRS or state agency. But unlike the email, you won't receive a text message acknowledging that you have e-filed.
If you signed up for text messaging but didn't get any, your return wasn't accepted/rejected yet, or you may have entered the wrong phone number in TurboTax. Regardless, you can check your efile status by clicking here and following the instructions.
And if you received a text message that doesn't belong to you, the intended recipient probably entered your number by mistake. No need to worry; refer to the section above for more information.
