I have a market discount adjustment of $4620 (US Treasury note redemption) on my 1099-B that should show up as interest on Schedule B. When I entered my 1099-B information one transaction at a time, it showed up as $4620 as expected. However, when I used the summary method, it showed up as $3346. That also happened to be the realized gains (proceeds minus cost basis of all my transactions). Is this a bug or a user error?
