When it asks me to review and "enter amount disallowed under Wash Sale....." i try to leave it blank to disallow the entire loss it still asks me to come back to it?

I linked to Betterment and at the end when reviewing it asks me to enter the amount disallowed under wash sale rules as it pulled in 0 so I have to update it. I try to update and leave blank to disallow all but it continues to ask me to come back to the same entries. No matter what I put in the box it won't let me continue
