K1 & Partnership income is best entered in Profile > Net Worth > Business card. Here, you can select the business type as either an S-Corp or a Partnership.

The income can then be entered in the Distribution field. You will see this amount as an income inflow within the Cash Flows. This income will not be subject to FICA tax. Any portion of the K1 income that is to be subject to FICA tax can be separated and entered in Profile > Income with a Salary card.
