Thanks for asking your question! I'm sorry to hear about your tax issue and I'm going to try my best to help you understand or resolve it.
How are you today?
Unfortunately, as that tax return is very old, it's possible that the IRS no longer has a copy of this return. However, you can certainly send in the request for the information and see if they do.
To see if they have a copy of the return, you would file form 4506 along with a fee and request the return. The IRS will process, and let you know if your return copy is available
You can receive form 4506, here: http://www.irs.gov/pub/irs-pdf/f4506.pdf
