received the same letter, but mine showed four different transactions totalling up to just over 3,600. Of the four, one was for just over 2k in a year that I know that I didn't send a wu for that amount.
After reading more info on the website for the settlement, it said that after you give them your info, then whichever state that the money wasn't collected in, you will receive a claim form for said state. I just threw it away thinking either scam or trap.
