Also, the 8958 will split everything, and then one person has an addition and the other has a subtraction. In ProSeries the numbers for the 8958 do not carry to anywhere. But I think the total addition/subtraction is supposed to carry to the "other income" line. Is that right?

Still totally confused how to handle the Federal withholding, how to get it onto the tax return.

These two better get married. This is nuts.
