File association problem with 2017 tax return - technical advice needed

I need to open the 2017 TurboTax return that I copied from my old computer to a newer computer, but I'm having a bit of trouble because the new computer incorrectly associated the saved .tax2017 file as an Adobe file. I think the incorrect file association happened because I had not yet installed TurboTax 2017 to the new computer before I tried to open the .tax2017 file. Now that I have installed TurboTax Home & Business 2017 onto the new computer, I can open the file - but even after saving the file my computer did not change the file association to TurboTax. I suppose it is a nit problem, but if anyone knows how to change the file association in Windows 10 I would appreciate the help. When I right-click on .tax2017 file and select "Open with..." from the menu, I can't seem to find TurboTax2017.exe.

Thanks!
