I remember this being an issue a month or so ago when filing from within the return (Ive never Efiled that way, I have no clue how it works) but some people were able to get it to go through using the EFCenter, but not all.......I feel like there was some other "trick" support had someone do to get it to work again back then....but I cant find the right keywords to pull up that old thread again...and this extra long tax season has overloaded my mental rolodex for issues like this, sorry.....you may be stuck waiting until Monday when support opens.
