Depreciation tracking now that forms aren't provided

I own a duplex and have rented out one side for most of a decade.  I had family living in there for a few years, and we made a lot of improvements over the years, so there were a lot of different amounts that started depreciation at different times, and none of it occurred smoothly.  Needless to say, it would have been a recordkeeping nightmare if it weren't for the Depreciation and Amortization Report that used to be provided by Turbotax every year.  That document saved my butt every time I switched from CD to online version, or went back to Turbotax after a particularly complicated & busy year convinced us to use a CPA instead of Turbotax.   

Now I'm bac to Turbotax & find that they don't offer that form anymore, saying that everything is just filled in automatically.  But since you also don't provide a Form 4562 for properties unless they are new, and you lump all depreciation for each property into one lump sum, I no longer am able to find any way to track the amounts that applied to each improvement, as I will need when I sell it.  

Please help me find the actual depreciation amounts that were calculated for each improvement.
