If TT said you had to mail in the return then you were not eligible for efiling AND you cannot amend a return that has not been fully processed (and you cannot efile a 1040X because the original return was not efiled) SOOOO all you can do is wait for the paper return to be processed which will take much longer this year to do as the IRS is short on human manpower and overwhelmed with tasks so they are millions of returns behind in processing.
