I have an investment that was sold that has accrued market discount in box 1f. TT shows it in Part III of the worksheet but not in Part I of the worksheet where it should be as well, and since it's not there, it's like it doesn't exist for calculation purposes. Other investments that had a value in box 1f show up in both places. Why wouldn't this one? And how would I be able to get it to show up in Part I if you can't manually edit Part 1?
