So you purchased desktop software for 2018?
You can get the 2017 data into the 2018 return. I will tell you a couple of ways one might approach this.
If you used Free Edition last year, however, the *.tax2017 will likely be locked. Here's a way to get the 2017 data into a 2018 tax file, which is to start a 2018 online return just long enough for it transfer 2017 data into the online 2018 return. Then one could download the *.tax2018 and OPEN it in the 2018 desktop software. To use that method, see this FAQ and choose the "transfer from online" instructions.

Or here's another method. You can download your *.tax2017 data file from your online account once you unlock it as I explain in this paragraph.
Then, when you start a new 2018 return in your desktop Deluxe software,
you can have the program transfer-in the information from the 2017 data
file. But with this method you would need to first phone TurboTax Support and tell them of your 2018 software purchase and ask them to unlock your prior returns. I would probably try this second method, since it will automatically give you access to all your prior online returns until the end of October (possibly of 2020, but I'm not sure, could be 2019 in this circumstance.) But in any case you can get the 2017 data file to use for this purpose.
