Non-taxable 1099-misc income

I received a 1099-MISC for Capital Credit Refund from a Co-Op for my parent's account upon their death. The refund was for money they paid 100% for residential services, and never deducted from their taxes. The Co-Op suggests I just not enter the 1099-MISC information, but, instead include a written statement referencing the amount, payor info, including FEIN and why I did not include the income. How do I include that statement in TT Deluxe? Will I still be able to e-file? I initially entered the info as income and then added an "other income" entry with an equal NEGATIVE number to bring the net amount to $0. When I attempted to do that, my return became ineligible for electronic submittal. I would like to use the e-file method if possible.
