How do I answer the question on Schedule C part K about the Net income allocable to qualified payments from agricultural or horticultural coop? I have tried putting 0, 0.00, -1, leaving the field blank and continue getting the error message on the review. I have tried the different answers from the posts with no luck.  This error msg will not allow me to e-file my taxes. The token number is 684638.  Please call/email me with a resolve for this error.  Thank You!
