... In my view, there is nothing that should be done in this situation unless and until the taxpayer receives a letter of inquiry or Notice of Audit.... If a taxpayer or representative were to contact the I.R.S. about a filed return first, say to explain a Form 1099, their chances of being audited would only go up, thereby asking for "trouble".Steve (Warmglowingtubesart), thanks very much for your informative posts. But note in the OP the indication that the items were sold "within this year." So presumably what is being looked for is guidance about how the sale proceeds should be treated when the 2016 return is prepared a few months from now. (And perhaps also if a final quarterly estimated tax payment for 2016 will be submitted).
