Having been through it I will echo bwnbwn - Don't volunteer anything! Keep your responses short and to the point. If you start mentioning affiliate accounts or Adsense accounts you can be certain that you're going to have to produce them. Just keep all your 1099's together and don't open any unneeded doors.
Most important... do not lie.
