We have turbotax premier and have mostly finished our personal tax return. My wife and I own a small business, partnership LLC. How should we proceed with business taxes?

If you need to file a separate 1065 or 1120 Business return, You need Turbo Tax Business.

The small business program (TT Business) is for 1120 Corporation, 1120S Corp, 1065 Partnership or 1041 Estate/Trust returns and will not do your personal 1040 return.   It  is a separate program from the Desktop Home & Business program or the Online Self Employed version.

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.

In addition to what @VolvoGirl has stated, if you live in a community property state, you have the option of not filing the partnership / LLC assuming it is taxed as a partnership under the default rules.

Community property states are Arizona, California, Idaho, Louisiana, Nevada, New Mexico, Texas, Washington, or Wisconsin. 

So unless you reside in one of those states, I will not go into the details of the rules to avoid filing a partnership tax return.
