Thank you, @SantinoD for the thorough response. I had actually found that thread when I was searching for an answer. And while having offsetting amounts on Line 8z might be an acceptable workaround, it is not exactly what the IRS guidelines specify. That's why I was asking the question - I had hoped to be able to report exactly as the IRS has specified, with the total sale amount on Line 8z and the offsetting number on Line 24z.
