Disallowed wash sale amount (leave blank if entire loss is disallowed)

When I make a stock sale on TurboTax which was a wash sale

Under: "Any of these less common items on your 1099-B?

Box 1g Wash sale loss disallowed   $56.86

 

Two pages after, the sixth line gets prepopulated.

Under: "Select any less common adjustments that apply"

[check box] Loss from this sale is disallowed due to wash sales rules

        Disallowed wash sale amount (leave blank if entire loss is disallowed[$56.86]

 

If I leave it blank (delete it), then the previous entry from Box 1g also gets deleted. 

Should I just ignore this message "Disallowed wash sale amount (leave blank if entire loss is disallowed)"?

 

Please explain.

 

Thanks much!
