You would have to liquidate only all of your traditional IRAs, not your Roth IRAs, to be able to report on Schedule A the unrecoverable basis in your traditional IRA. But to be able to get this deduction by liquidating all of your traditional IRAs, your distributions of all of your traditional IRAs to do so would have to have to total less than $15. Your deduction would be, at most, $15, the amount of your basis (rounded to the nearest dollar). The rest of your loss will simply be money on which you never had to pay taxes.
