Investors & landlords

Yes, I did enter in 2020 and they pulled over in 2021.  I believe I just found my error and it is in my head!  It seems I was trying to adjust the basis of my structure for the cost of the roof and renovations when in fact those basis adjustments were made to the actual assets in Part II of form 4797.  Those assets show in part II because they were held less than 1 year.  If I were to somehow force the roof and renovations costs into basis of the structure then I would be double counting those costs.  Does my assessment seem accurate?
