Not sure if this will help you but I was having the exact same problem and I had already paid so I figured I'd have to wait it out. I must have tried AT LEAST a dozen times if not more from my home computer to fix it with no result. I tried just now while on my lunch break FROM MY PHONE and I was able to correct it on my first try. Could be coincidence but I was able to file and my return is already accepted. Good luck!
