There is no answer that I know of. TurboTax only supports for 3 years (the standard statute of limitations for a refund). Even if you could find the software somewhere is will not run or be usable without updates that are not available.
Some people that need printouts have used the online "taxprinter.com" (that I cannot vouch for) but they are expensive. They say they can print any returns using the .tax data file since 1994.
