I usually attach a copy of the broker's statement and just enter short term gains and long term gains on the Schedule D, referring to the statement for details.
This year I am downloading all the information into the return. There are 400 transactions. H&RAH requires me to go through each one and "edit" it; but since I have no independent information, it is both pointless and incredibly boring. On one I hit "delete" rather than "edit" and had to reenter the information.
I have have done that more than the once I noticed... This year I had a capital loss, so they don't really affect my 2012 taxes, but will in the future as carry forward.
If I accidentally deleted one that had a profit on it, it would not affect anything this year, but hopefully would next year. Is this something the IRS would notice; all were reported to the IRS by the broker.
Hopefully I didn't delete any of them, and if I did, it will likely be less than $100 in one direction or another. I don't really want to spend a few more hours looking for an inadvertent deletion, but don't want to get in trouble with the IRS either.
Would the IRS pick up on an inadvertent deletion, and if they did, are there any consequences other then a couple dollars tax one way or another?
