2016 is pretty "iffy" since TurboTax saves returns for seven years. After seven years they are gone.
You have to access your own account and/or print it for yourself using exactly the same account and user ID that you used when you prepared the return.
Start a 2023 return online and enter some personal information so that the menu on the left opens up and lets you access your past year returns.

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.
