If you have a partnership LLC you will need to use TurboTax Business to file your partnership 1065. This will generate a k-1 for each of you.   The K-1 is entered on your personal return by:

1. Click on Federal Taxes
2. Income & Expenses
3. Scroll down to Business Investment and Estate/Trust Income and click Show More
4. Click Start next to Schedule K-1

If on the other hand, your business is a sole proprietorship or a Single Member LLC (not required to file 1065) you will then just need to use TurboTax Self-Employed which will take you through the steps to fill out a Schedule C.  If this is the case, you will not have a K-1.  

How do you utilize Quick books for the LLC  Tax information, which has its own email and login information, when filing as a sole proprietorship under my existing email login that I've used for a decade?  

My LLC is a Side business, while my main income is from a W-2 job ive had for 13 years and used turbo tax for.
