No. It simply means that your return was selected for additional scrutiny. This usually happens for a reason, but it can also be completely random. Just write down everything the website says and follow the instructions. If you call us to help you with it, be sure to have this information ready.
Please remember that this is usually no big deal and you did not necessarily do anything wrong. For example, in one case a client was getting the Earned Income Tax Credit and one of her qualifying children had a different last name. There are all sorts of valid reasons for this. However, because this is sometimes an indicator of fraud or ID theft, the IRS selected her for some extra questions. She faxed them a couple of documents and got her refund within two weeks. In another case, a client couple adopted a special needs child. Because this qualifies for the maximum adoption credit, it's an area that gets abused a lot. The IRS asked for some adoption paperwork, the clients faxed it to them, and then got their refund within three weeks. In neither of these cases was the taxpayer at fault. However, because their tax situations were statistically likely to be similar to those used by some criminals, the IRS selected them for slightly closer scrutiny. Most of the time, this is why this happens; and most of the time, these issues are resolved quickly and painlessly.
