As DoninGa mentioned, if you filed with TurboTax last year but used a different email address and account, your AGI might be there. Try signing in with another email address, or find out how to access your other accounts (you'll need to sign out of this account first).
If this doesn't work, you can also get the information from the IRS or mail it in your return. See the link below for more information.
