TurboTax Support will not phone you from this user forum, but we can tell you how to use the Live feature at TurboTax Support when they are open tomorrow. They open at 5AM Pacific (8AM Eastern). I'll tell you how to do that in a bit.
But first, this forum may be faster. I may be able to help you find your 2017 return right now. How was it prepared--in Online TurboTax or the desktop software (CD/download)?
If it was prepared in Online TurboTax, log in and go the section "Your Tax Returns and Documents". Expand that section, and choose tax year 2017. Is the 2017 return there? If so, what happens when you click on "download/print the PDF?" Can you download it, or does it ask you to pay? Is there also a clickable link there that says "View adjusted gross income (AGI)"?
Or do you find no evidence at all of a 2017 return in that account? If not, then you likely have multiple accounts (User IDs) without realizing it. We can help you troubleshoot that to find your other accounts.
