TurboTax (and the IRS) saves tax returns for seven years. After seven years they are purged. In order to look at your past returns you need the exact account and user ID to get in to the account. No one else can get to them for you. You might have more than one account that you used, so try using the account recover tool.
Many people have multiple TT accounts and forget how to access them. Log out of the account you are in now.

Or did you use the desktop version of TurboTax? If so, the files are on your own hard drive or any backup device you used like a flash drive.
