How to enter Accrued Market Discount for Treasuries when cost basis is the same as proceeds on 1099-B?

This year I got a 1099-B for a T-Note that matured in 2024. The cost basis (1e) and proceeds (1d) are the same and AMD (market discount) is listed in box 1f. When I enter all this info, TT doesn't doesn't add calculate/any tax for the market discount in 1f. I know this is not correct. How do I fix this?
