Since you are a 2-member LLC, you should file a Partnership return (1065) (unless you're organized as an S-Corp.). To prepare a 1065 you will need TurboTax Business. You can visit the following link to purchase the program: TurboTax Business.
TurboTax will take you through an interview to prepare the business return, similar to the personal (1040) products.
As part of preparing the 1065 return, TurboTax will prepare K-1 forms for each partner. You will need to enter the information from the K-1 into your personal 1040 return.
