Investors & landlords

In my case, TT's rounding ends up showing a gain of around $200 less than my 1099-B.  Even if the IRS is fine with that, it's just luck it was $200 less rather than $200 more.

Completely unacceptable, and makes the software I paid for (desktop edition) useless, as I will not submit a gain to the IRS different from my 1099-B.
