No, TurboTax does not provide its users with attorneys. Your son made an extremely common mistake. We gets requests for help all the time from parents whose dependent kids incorrectly said on their tax returns that they could not be claimed. The remedy is to file your own return that claims him and file it by mail. If you mailed it and the IRS says they did not receive it, then mail them another copy of your return. You have not mentioned how long ago you mailed the return. It typically takes at least three or four weeks after mailing the return for a human to open the envelope and enter your information into the system.
Your son, meanwhile has to wait for his return to be fully processed and then amend to change the way he answered the question about whether he can be claimed.
