Go back to the K-1 interview and cycle thru until you reach the box 16 drop down box with the entries.
To delete 16 I, put the pointer on the amount and delete it. Then put the pointer on the descriptor to the left and click on it. The drop down menu will appear. Scroll up to the top where it is blank and click on it. That will delete the descriptor. Both the amount and the descriptor must be deleted to clear the error.
