I got it; I think. I found the closing price of the GLD on the date of the confusing transaction. That gives me the value of my holding on that date. Dividing the proceed value to my holding gives the cost basis factor. This is very close to the given factor in 1099B. Thank you for your response.
In TT, there is a "needs review" button for that transaction, the only way to get rid of the button is to enter a value for the cost basis. I entered zero and TT accepted that, but that is not correct; is it? I did the following to calculate the cost basis for this transaction:
[Total Net Asset of the Trust] = [Proceed] / [Cost Basis Factor]
[Cost Basis] = [Total Net Asset of the Trust] / [No. of Shares Bought]
I appreciate your input.
