I held ISO, ESPP and RSU stocks from Atmel before it was acquired by Microchip in April, 2016. I found no area in Turbotax to enter additional information as 'Merger' or 'Cash in lieu' for each lot of sale. Somewhere within this community, I saw the answer to calculate the gain as: the lesser of cash received or the tentative gain which is the proceeds - cost basis of the acquired stock. For example, the ISO sale lot that I enter has the tentative gain which is more than the cash received. But Turbotax chooses the tentative gain to calculate the actual gain. So please help and clarify how this gain is determined. Thanks.
