If I have an LLC Partnership, does my partner and I need to file a combined return or two separate ones?

I have an LLC with a partner and was planning on using the TurboTax Home and Business software to file LLC taxes. I am confused if my partner and I need to file a return separately or if we would file just one return? We had gotten an extension for the 1065, and need to know if I need to buy two copies of the software or if one would suffice. Thanks
