My turbo tax account says I didn't use turbo tax for 2017 and I did. I can't transfer my info over to 2018. What went wrong??

You probably started out in the wrong account instead of the account you used to prepare 2017.

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.
