There's a big difference between received and accepted. We tell you when we have received your return. The accepted message comes from the IRS and we pass it on to you.
Every year the IRS takes a few returns early to test their system for the year, so it's possible you received an accepted message because you are part of that early batch. If you have an Earned Income Credit or Additional child Tax Credit, though, the IRS will not be able to process your return fully before 2/15. They are required to wait until then by a new bill Congress passed. The IRS really does not have any leeway around it, unfortunately.
