If you never prepared the tax return, you must buy, download and install on your computer the 2018 program to prepare a 2018 tax return. Here is the link to buy it: https://turbotax.intuit.com/personal-taxes/past-years-products/
The 2018 tax return can no longer be efiled. You must print and mail it yourself. TurboTax does not print and mail it for you.
