Cannot edit entry while doing the final review to check for errors

Hi,

I have 14 errors to complete the review to fix which are all the same entry type.

Form 1099BWorksheet.

Accrued Market discount should not be 0. Enter amount disallowed under wash sale rules, or leave blank if entire loss is disallowed.

Disallowed wash sale amt 0

The entry is 0. I can't edit this entry or remove the X.

Any suggestions?
