I dread returns with sales of rentals, especially the first one I do every year when I have to remember all the steps that are supposed to make it "easy."  On the Schedule E worksheet you check a box. Then on the Asset Entry worksheet you enter details of the sale.  The problem is that you usually have five or six asset entry worksheets, including the 2013 roof and the 2016 A/C.  Obviously, these components were not separately stated in the sales contract.  Maybe there is a way to combine all of them, without adding them all up and changing the original worksheet manually.  But I haven't found it yet.
