if you e-file the return is transmitted to the IRS/state by Turbotax. if you chose to mail it, that's a do-it-yourself project.
on an e-filed return, you will get two e-mails the first will say submitted. the second will say accepted or rejected. accepted means you're done. rejected means there' an error that needs to be fixed, if possible. if fixed, you can re e-filed. if it can't it will have to be mailed
