Should I use a different Turbotax program this year? I used the Personal and Business program for many years. I didn't do any business in 2017. I did have investments.

TurboTax Premier edition will suffice when you have investments.  

Here is the link to the TurboTax Premier 2017 Online version information:

Let me add a little more info to @TurboTaxJulieCo 's answer:  If you officially closed your business in 2017, or if you had business assets that you were depreciating prior to the close, you'll need to account for the "disposal" of those assets.  To do that, you'll still need the Home & Business program for one more year.  If not, Premier is indeed the edition you'll need.
