TurboTax does not support tax year 2014.
If you started a 2014 tax return using TurboTax then the PDF download will only have the forms and schedules that are required to file a tax return. There will not be any worksheets or information only pages in the PDF.
To access your current or prior year online tax returns sign onto the TurboTax website with the userID you used to create the account - https://myturbotax.intuit.com/
Scroll down to the bottom of the screen and on the section Your tax returns & documents click on Show. Click on the Year and Click on Download/print return (PDF)
