Pretty much so. I'm in the same situation with an old copy of 2015 Turbo Tax returns, but I am not able to open the 2015 Turbo Tax software I actually just downloaded from my website that stores all of my previous downloads. It crashes because of some JAVA changes Apple made in their subsequent OS software and TurboTax has no workaround.
I thought I had saved a PDF copy at the time, as I do every year, but cannot locate that copy so I'm pretty much screwed. I hope you have better luck.
