the problem is the name is your mother's but the social is yours. the irs has no way of knowing if the name is right and the social is wrong or vice versa. so it may just be ignoring the return - both of you better hope this is the case because there are worse case scenarios in this situation. what you should have done was to cross out your mother's name and entered yours but even that might create issues with the IRS. I know of no reason that TT wouldn't allow you to change name. I'm sort of surprised that neither of you received IRS correspondence about this matter. anyway, you can't file a 1040-X because correcting a name is not an option. that leaves calling the IRS and asking for guidance. call early in the day, because you could be on hold for hours.
one other possibility is to contact the IRS tax advocate in your state.
