Trouble amending return to include K-1

I received a K-1 unexpectedly after filing.  I have entered the data from the K-1, and have encountered problems:  the first was I needed to add a second K-1 for box 16 lines F and M and removed those from the first K-1( I think, and did so); the second is now I am getting the error message:   " 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 sourced at the entity level."                       I thought this is what I fixed?  There was a nice answer to a nearly identical question that indicated that one needs to click a check box to "elect to forego completion of form 1116" since there was not any foreign tax paid;  however, that is not an option, it seems, in TT Online Premium.  I've tried adjusting the amount from box 16 line b to remove the amount included on the second K-1, but that wasn't the solution.   How do I fix this?  Do I need to just get the paper forms and fill them out?
