I too am waiting. I filed the evening of 2/7 with the "24 to 48 hours" message. It's now 2/10 at 7:40 pm CST and still Pending. I did however get in touch with a TT support person who was able to confirm to me that the IRS has my return by giving me a confirmation number. I told him this is the longest I've ever had to wait but this is the latest I've ever filed. I have the Energy Tax Credit and that form was delayed. The support guy said they're being told some are taking up to 5 days to be "accepted."
I wouldn't think filing with someone else now would be a good idea. It could appear fishy. But if y'all try and talk to a support person, they may be able to shed some light.
EDIT: Well, I had no sooner posted this when I finally got an email saying my return was accepted. Filing was on 2/7 in the late pm and today is the 10th.
