Missing Info on 1099B

My 1099 shows 2 sale dates of IAU but my activity on my account summary does not show any "sales" of that security. How do I determine a "cost basis"? These 2 transactions also show up as a "Gross proceeds investment expense.  Running premier Turbo Tax and it cannot figure what to do with the 1099B that I imported from LPL Financial. Any help would be appreciated. The proceeds from these 2 transactions amount to $3.20.
