True ... but my answer was posted before OP said 2009 ... and I say you were responding so I waited for your SOL answer that I knew was coming.   Not sure how he could have possibly made all those payments all those years in any tax program unless he lied and said he still lived there.  A note in the program to alert users to their errors is not a bad idea but again the program can't do everything for every one all the time.
