How do I create an additional K-1 worksheet?

To create an additional K-1 worksheet,

• Type "K-1 in the Search window.
  
• Click on "Jump to K-1"
• Click on Start or Update next to the type of K-1 you received
• If you've already entered a K-1 of the same type, click on "Add Another K-1"
  

When TurboTax checked the return for errors, I get a message of "Check this entry".  It reads "Sch K-1 Wks-Partnerships: Box 16 Description -1 has been entered for more than one type of income.  Use separate K-1 worksheets to report more than one type of foreign gross income source at the entity level. I don't know what this means and what I should put in. This is first time dealing with Limited Partnerships, K-1 and am at a loss.

If you have more than one entry in Line 16, delete one of them.

Part III, Line 16 on this K-1 from Merrill Lynch has codes A, B, C, D, and F.  It also shows an E with a - (dash) and * which indicates "See attached statement for additional information".  I can't find any additional information on the statement (M.L. is not a big help).  I'm not sure I can just delete one of these entries since they are shown on the K-1. Doesn't this form go to the IRS?  Also, I'm not sure what "Box 16 Description -1 has been entered for more than one type of income" from the TurboTax message means. Thanks for your help.
