The letter called CP21B noted that they reduced my taxes that were withheld and increased my dividends and capital gains (I got a tax transcript). I still do not know what taxes that were withheld were reduced nor do I know what investments had increased dividends and capital gains. All dividends and capital gains info was downloaded from the brokerage company. I finally got to talk to a real person after being dropped by 3 IRS agents and after many 5-7 minute holds he told me he could not answer the questions and said that I would get another letter within 30 days explaining the details. I really doubt that any letter will answer the above questions. I am thinking of booking a sit-down talk with someone at an IRS office.
