what happened was you got paid 1800 in dividends that were originally classified as taxable BOX 1a. subsequently, the payor notified the broker that the dividends were nontaxable so box 1 had to be zeroed out (the paid/adjusted column) and then moved to box 3. box 3 does not have to be reported to the IRS - these are nontaxable dividends that will reduce your tax basis in the stock. if you didn't see the stock by year-end you should notice in some subsequent month, may be as late as March, the cost basis drops by $1800
if there is nothing else on the 1099-DIV (just box 1 as adjusted = 0 box 3 = $1800), the 1099-DIV does not have to be entered.
