Look in the Statement for your K-1. The 'F' income amount may be shown there. If there is no 'F' value shown, use the drop down and select 'F' and enter '0'. Try it. You need to fill out an additional K-1 Worksheet for each income item shown in Box 16. I had to use 4 Worksheets -- and my bottom line was not affected. When I entered the items on individual Worksheets -- I was finally able to transmit my return. Code F is shown or can be shown on the primary Worksheet. Only enter the Box 16 Income Line items on the additional Worksheets -- do not enter other Line items. You must, of course, enter the Partnership information.
