I just received a Corrected Tax Info Statement from my broker - I've already filed - listing a negative $XXX of OID on a US Treasury Bond which they say is a "Deflation Adjustment" and "may not be the correct number to report on your income tax return." It was not reported to the IRS and doesn't show up on OID summary page. At best, I am confused. Advice? Do I need to include it? File an amended return? Thanks.
