I suggest you delete the form 1099-DIV and re-enter it manually.
A simple way to delete forms in TurboTax online is to use the Tax Tools menu option, which is on your left menu bar when you are working in your program. Then, choose Tools and then Delete a form. Look for the form 1099-DIV in the list of forms and delete it.
If you are working in the download TurboTax program, use the Forms Mode on your menu bar to bring up the form you want to delete, then choose the Delete Form option at the bottom of the form.
