Form 1099-b, box 1F, turbotax will not accept F as a code

It's been a while since I needed to enter info for stock transactions. One part has me stymied. Form 1099-b from my brokerage has an amount in box 1F, "Accrued Market Discount". TurboxTax (home and business) has a checkbox with "I need to enter amounts from box 1F, box 1G or other.

If I check that it opens

Total Adjustments to gain or loss
List all adjustment codes

In the adjustment code box the hover lists many supported codes : B, C, D, E, L, M, N, O, Q, R, S, T, W, X

So, F is not supported, even though it's specifically mentione at the "I need to enter..." section? And it errors if I try to submit with F.

Do I skip entering the amount listed on the 1099-b?
