First, the error message said the problem was on Form 8615. There are no values entered on the 8615 (first box is checked), and right clicking on all of the empty boxes shows that none of them are inadvertently marked as estimated. Second, there are no dividends entered in any other form on this return. There were dividends last year, but this year the value is 0. When I look at "Interest and dividends -> Dividends on 1099-DIV" it shows "$0" for this year. When I click on the "Update" button, there are no 1099-DIV forms. When I create a fake 1099-DIV and then delete it nothing changes.
