I will definitely use the 1099-R and W-2 summaries because they provide an itemized listing of all tax slips. But the 1099-misc summary seems to give give just the total, which I already have. My client has 25 oil 1099-misc slips, and each year I struggle to make sure I have them all, it would be nice to have an itemized summary as you do with W-2's and 1099R's.
