Did you set up the LLC as a S corp? Then you need to file a separate Business 1120S for it. You will get a schedule K-1 from the 1120 return to enter into your personal return. So you have to prepare the business return first.
Turbo Tax Business is not available to do online or on a Mac. You can buy the Window's version here. And you can have both TT Business and TT Home & Business (or any personal version) installed on your computer at the same time.

But you don't seem to be sure it's an S Corp. you probably should go to an accountant the first year to get started right. If it's not a S Corp and only a single member LLC you file it as self employment on schedule C in your personal 1040 return. You will need to use the Self Employed version .
