You must mean your SSA1099. I have not yet received mine yet either. They arrive sometime in January, though. Since it is only mid-January, be patient.
You can check the Social Security site to see if it there yet.
HOW TO GET SSA-1099
If you cannot find your SSA1099,you can get one from your nearest Social Security office, or there is a way to go on the Social Security website and request one. Go to www.ssa.gov You have to create an account with a user name and password.
