So... nobody knows the calculation of how to do an aggregate nominee adjustment to split a 1099 in half when there are amounts in boxes 1a, 1b, 2a, etc.?
I'm surprised. I realize this isn't a common situation, but it certainly cannot be unique. People divorce and have to split investment accounts. There is a nominee process for this reason. The IRS provides one box to enter one aggregate adjustment. But zero explanation as to how to calculate that aggregate adjustment when the 1099-div reports income in multiple boxes.
I've Googled this and I'm not finding anything. I cannot believe there is not an answer.
