The 1099-B should list the basis.

Cost or adjusted Basis means what your beginning value was. 

If you purchased the stock, it would be what you paid for it (COST) 

If you inherited it, it would be the value of the stock on the day you inherited it. 

 

There are times when the broker doesn't have records of that, in which case you would need to provide that information.
