I am not a ProConnect user, so I don't know what your worksheet looks like.  I would have the same question, if what you describe is true (and I have no reason to doubt it), but don't let the perfect (or neurodiversity) be the enemy of the good.  Put it under investment property.  Reminds me of what my mother would say when the catsup would spread to the mashed potatoes on the dinner plate.  "It's all going to the same place."  On Schedule A, in this case.
