You only need a K-1 if this is an LLC with more than one member, or you have elected to file the LLC taxes under the rules for S-corps. In that case, you need Turbotax Business to file the 1065 return. That is a separate program from the personal version of Turbotax where you will add the K-1 to your other income and deductions.
Turbotax Business is available as a download to install on your own computer.

There is also an online version with Live assistance or Live Full Service but these are more expensive.
If this is a single-member LLC, you generally won't file a 1065 or have a K-1, you would file a schedule C attached to your personal tax return.
