That's normal for the vast majority of people who filed early. Except for a few returns that they pulled early, the IRS starts its normal processing on Monday, January 28 as I mentioned in my answer above. So you should hear something soon after that. It may or may not be on the 28th, since they will have a huge backlog that first day when they "open the gate" on Monday. So it could be a day or two later.
You should get an email when it's accepted or rejected. You can also check by logging back into your online account or by using this tool:
