I have an LLC Partnership (2 people). How do I file this?

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.

That requires filing a Form 1065 Partnership return. This is similar to a corporate tax return that produces a K-1 that you report on your personal return. That return was actually due on March 15th. So, just a heads up, you are likely subject to a late filing penalty.

TurboTax only handles individual returns with sole proprietorship businesses on Schedule C.

You will need TurboTax Business to complete a Form 1065.

Here's the link for that software:

***Note:  If the partnership is you and your spouse, you may be able to file on your 1040 with regular TurboTax. Please post a comment if this is the case.
