how to enter an llc partnership 401k contribution in turbotax home and business

I am using TurboTax Home and Business. I am a partner in an LLC with a K1. The K1 does not show my 401k contribution explicitly on the form, however it does reference it in the notes. What menu steps do I take to get to the proper form to enter the 401k contribution? Is it as simple as identifying the correct form and manually entering the information? If so what is the correct form?
