Use this TurboTax account recovery website to get a list of all the user ID's for an email address. Run the tool against any email addresses you may have used - https://myturbotax.intuit.com/account-recovery
If none of the user ID's received will access your account, then use the option shown in blue on the account recovery website, "Try something else"
If you never completed and filed the tax returns using the online editions and paid for either the Deluxe, Premier or Self-Employed edition, then you will need to download the tax data file for the tax return - ie Click on Download .tax file
Then you will have to contact TurboTax support so hey can push the installation file to your download account at no charge. You can then finish the tax return using the desktop editions. You will have to print, sign, date and mail the tax return as the prior year tax returns cannot be e-filed.
Support is open from 5am to 5pm Pacific time, Monday thru Friday

If you are referring to the TurboTax desktop CD/Download editions -
If you used the desktop CD/Download editions installed on your computer, the only copy of your tax data file and any PDF's will be on the computer where the return was created. TurboTax does not store online any returns completed using the desktop editions.
If you purchased the TurboTax desktop edition from the TurboTax website as a download then you can sign onto your download account and download the installation file at any time for any reason for up to three years from the date of purchase - https://shopping.turbotax.intuit.com/unified/downloads?route=myaccounts
