No, TurboTax has never mailed any tax returns. You have to do it.
If you want someone to help you with that Federal return error, are you able to phone TurboTax Support in the USA using an 800-number? Some countries don't allow it. I can tell you how, if you can. Or I can tell you how to contact TurboTax Support by Twitter or Facebook.
I will tell you in an answer below how to open the State return to finish it. If you mail the Federal return, then you'll have to mail the State return, too.
