Thanks Tom.
For the merger I was offered $11.80 cash per share for my current stock and 0.1612 shares in the new company (valued at $31.26 per share from merger agreement) for each share I had in the old company (valued at $16.8391).
I think my main problem is around Capital gain / loss.
So for example my old shares had vesting accelerated and I was taxed at:
497 shares x $16.8391 = $ 8369.0327 Taxable income Restricted stock awards and units
but on my 1099B
497 shares x 11.80 = $5864.60 Net Proceeds. The cash portion offer of the merger agreement
In Turbotax its calculating 8369.0327 - 5864.60 = (2504.4327) has a capital gains Loss
There is no way to account for the value of the new stock also received as part of the merger 0.1612 x 31.26 = 5.0391 in Turbotax. The stock portion of the merger agreement.
11.80 +5.0391 = 16.8391 = valuation of my old shares
I think there should in essence be no net gain or loss. I need to try and find away to represent this in Turbotax
