follow the IRS instructions
Do: If this transaction is reported on a Part I with box B checked at the top or if this transaction is reported on a Part II with box E checked at the top, enter the correct basis in column (e), and enter -0- in column (g).
personally, with type B and E transactions meaning the cost basis is not reported to the IRS, I put the correct cost in column e if needed and enter no code in column f or anything in column g
