I sold shares in a Vanguard fund that charges a fee when shares are sold less than 5 years after purchase. I received the NAV of the shares, less the fee.
Vanguard's 1099-B gives the NAV as Gross Proceeds and does not mention the fee.
Can I add the fee to my cost basis, or is it (alas) a Schedule A miscellaneous deduction subject to the 2% limit?
