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.

What are you doing that requires the 2017 AGI?   I just want to be sure you're not trying to prepare a 2018 return in Online TurboTax, which is only for 2019 returns.   A 2018 return can only be prepared in desktop software (CD/download) and cannot be efiled.
