You have been selected for examination. It might not have been assigned to an examiner yet. When it is assigned, it will be reviewed according to the project code. You will likely receive a letter requesting information related to your exam. Your best option of it has been so long is to contact Taxpayers Advocates. They will contact the IT'S on your behalf to get someone assigned to your case and request that they start it.
