1099-B and cost bases

[Sheri71]

We inherited stocks and got a 1099-B form.  It has no cost or other bases.  I do have the last account statement from the company from when we sold it.  It has the transaction type, gross amount, net amount price per share and shares increased or decreased.  Does this statement help compute the cost bases, or do I just allow turbo to deduct what it needs to base on the 1099-B form.  We have no other information on the sales.

Calculate the cost basis for inherited stock by determining the fair market value of the stock on the date of death (or alternative date if chosen by estate). You can find this information on historical records of the stock ticker symbol. 

Inherited stock receives a stepped up basis, so this could potentially lower or eliminate your gain depending on how soon after death you sold the shares.
