the IRS too only retains returns for the last 6 or 7 years so they likely won't have them for years prior to 2015.
there are websites like https://www.taxprinter.com/ (we don't vouch for them but many have used it) there's a fee of $45/year $80 if you also want state for that year.
some websites offer used Cd's for those years. there may be no valid license and Turbotax doesn't offer updates or state returns for years prior to 2019 so installing and opening the old .taxXXXX file might actually change the return from what you filed.
in the future, since hard drives/computers do fail save a pdf on your desktop and a second on offline storage - either the cloud if you trust those websites or use a thumb drive.
