On 3/5/12 I efiled my tax return and received an email advising that I had already filed a 2011 tax return. I called the IRS the following Monday and was told that I filed a return the 1st week of Jan 2012. I told the person I spoke to that I had not filed a return at the time because I did not even have w2s available or mortgage information to file a return. I was then told to fill out paperwork for identify theft and attache my return, which I did. Every time I call I get a different story about where my return is in the process. Yesterday I was told that I made an error but have never received a letter from the IRS. I was told that it was because my address changed and I need to fill out a change of address form. Everyone I speak to is rude and condesending as if I am the liar.
