Assuming you are using Desktop software??
1) Windows: Click into box 1a, then rt-click on it to get the pop-up menu, and select "Add Supporting Details"
2) MAC (I think, but this also works on Windows): click in box 1a, then go to the top of the screen and select "Edit" to get the drop-down menu, and select "Add Supporting Details".
___________________________
The Double-click method sometimes works if you are re-using a 1099-DIV that transferred over (but empty) from last year, that already had a Supporting Details sheet in it for that same field.....but doesn't happen if you are creating a new 1099-DIV. 1) and/or 2) above always work.
