Had an experience with TTax and the IRS about 10 years ago that altered my way of filing. Had been filing with each security listed and the corresponding dividends for each. For this particular year I had changed brokers in mid-year [simply transfered securities] so had two
1099's that year - with individual securities dividend payments spread across the 2 1099's. My totals were ok but IRS had difficulty resolving between the figures reported on my Sched B and the figures reported on the 1099's [I too had a little difficulty resolving]. Received one of those ominus inquiries from the IRS requesting clarification of my Sched B/1099 info.
I wound up revising and re-submitting the Sched B to match the 1099's. Didn't cost me anything - other than time, postage and a little anxiety!!
Now always file listing the broker as payor - with the totals as the broker reports. This is essentially what QW/TTax is doing. For documentation purposes, I usually go into TTax [Forms View] and enter the individual security data in the 'Supporting Details' forms.
