1099- b Cost basis left blank from computershare

We received our 1099-b from computershare. There are 3 "sales" on it. One does not have the cost basis and the box is marked for "non covered Security" When I go into EQUATEPLUS which handled this for Computershare under Documents, Then in Transactions , then under US Tax form supplement

 There are there is a breakdown of the sale. Covered , Non covered short and long. Under the uncovered long term they have a total about of shares sold with  the amount under the tab  "reportable cost basis" . 
is this the amount we can use ?
