The 1st half of 2017 I operated as a Sole Proprietor and the 2nd half I operated as a LLC. Can I still file my taxes with turbotax or do I need to have turbotax business?

What kind of LLC?  If you are a Single Member LLC you still report it on schedule C in your personal return.  If you elected your LLC to be an S corp you need to file it on a separate 1120 S business return.

I am a single member llc

I think I am.  How do I make sure that I am a single member llc?

You might need both.  

You will need TurboTax Self-Employed online or Home & Business desktop for your self-employed business.  You will also need the TurboTax Business if your LLC is one of these: Partnerships, S Corp, C Corp, multi-member LLC, trusts, and estates
