You can't efile with errors already highlighted in pink. I greatly use the pink errors and also the yellow error triangle icon at the top. It was countered last year that it never hurts to have an extra layer of error checking, but the boxes do slow me down, do not in reality provide protection, and are just an unnecessary annoyance. The one place I wish I had error protection (other than the efiling bouncing back) is in Virginia when I neglect to put in the date for withdrawal of tax.
