Well ... if you used the 2017 Online program and didn't pay the Online fee then you need to buy the 2017 program to complete the 2017 return. If you just bought the 2017 downloaded program then you need to contact TT support to get the online program unlocked so you can access the .tax2017 file.
Contact
