Capital Losses Not Offsetting Capital Gains
From the web for Turbo Tax: Yes, but there are limits. Losses on your investments are first used to offset capital gains of the same type. So, short-term losses are first deducted against short-term gains, and long-term losses are deducted against long-term gains. Net losses of either type can then be deducted against the other kind of gain.
This isn't happening on my return, as I am paying tax on long term gains/distributions than are more than offset by short term losses.
