In my situation, I have $228 of investment expense in Box 4B1A. This is US-based investment expense from my K1s. In 2024, this was marked as US based and I didn't have to fill out the additional boxes below. This is no longer marked this way or at all. Should this value even be in the noted box since it doesn't apply to foreign tax calculations?? This US-base investment income is what is driving the need for Boxes4B1B and 4B1C ro be populated by me.
