Hang up on 1099-B work sheet

I'm trying and file and it keeps bringing me back to the Capital Gain (Loss) Adjustments work sheet.  I downloaded the 1099-B from the broker and one asset has a $04.2 loss that it's flagging as a wash sale. It tells me to leave the line blank if it shows a 0 BUT it won't let me change the entry so I can't file the return because it thinks there's an error.  How can I change this I'm HUNG!

Thanks Bob
