The third example is how it should read. That would reflect your Cost basis that is then worth 0, implying a loss, which is the same as a negative number for proceeds. I don't know how many of those entries you have, but I have 86, and there is no way I will be manually changing all of those after paying money for a service that should do it for me.
However, this is a perfect example as to why us, as end-users should not be making these changes. We are not tax professionals, and the software needs to be what takes care of this for us- that's what we are paying for after all, isn't it? By us trying to decipher the way it should be, that is adding tons of potential for errors, issues, and possible audits.
