You can not change this in the review. A wash sale of less than 50 cents is automatically rounded to "0" by TT which is not an acceptable entry. Go the the income section and you can override the amount. The box cannot be zero, but you can delete the "0" and leave it blank. If you have a large number of sales in your 1099-B (over 1,000) turbo tax may crash when you try this.
