This was my exact experience, TurboTax never submitted my return for 3 days and they lead me to believe that they did. I could not get a hold of anyone to tell me what the case was. On day 4 I was notified that my return was submitted. Immediately after that I was able to very on IRS website that my return was pending with them. Very misleading and stressful to sit there and wait for the IRS to accept within 48 hours when TurboTax had not even transmitted my return. All of Turbotax message board responses and status "pending" was not helpful.
Next year I won't be using this service any more.
