Question one.

If box 7 is more than box 6, do I have to reduce box 6?

Question 2.

If there is an amount in box 6 but no numbers in any other box can they still claim the deduction that is in box 6?

Question 3.

When the program asks "net income allocable to qualified payment from agricultural or horticultural coop" how or where do I find this number? Is it on the 1099-patr? 

I believe it comes off of box 7, but what if there isn't a number in box 7, then do I just put 0?
