Deductions & credits

I never received a 1099-S notice...and from what I understand they wouldnt issue one if it was under $250k in profit. They sent another reponse and are allowing me to reply, with 'sufficient evidence' that I only profited off my sole and primary residence $50k, by MAY 8. My question is how do I go above providing them with copies of original HUD-1 and final settlement statements from the sale. The address was listed on my Drivers License, Tax return address, and voters registration during that period.
