Get your taxes done using TurboTax

But stop beating yourself up....IF your brokerage didn't report the redemption on the 1099-B/8949....and if you are really nervous about not reporting it....then go ahead and do so. 

Then it's reported and you can stop worrying about it.  It shouldn't affect anything with a zero$$ short-term gain/loss.
