Thanks. That makes sense. They do not provide a department and an address to receive written responses to the notice. The address on the letter head of the notice is in Austin, TX, but IRS website says to mail 1040-X to Kansas City, MO (I live in NY). Any suggestions on where to send the IRS your recommended letter? Also, my sister just got the same notice. There could be an error in the way TurboTax transmitted the information when we filed?
