Since you cannot get or install a 2002 program any longer the .tax file cannot be read. If you didn't keep a PDF of the return then you can pay for a company to convert it to a PDF for a fee (and a risk). What could you possibly need from a return that old ?
A state ? Are they really asking for a return that old ?
If you have old .tax files you can try converting them to pdf files at Www.Taxprinter.Com
They are not connected with Turbo Tax. Use it at your own risk.
