TurboTax is telling me I can't enter a negative number, for an option spread, but that is wrong. How to fix? Also wont allow 0 for washsale and won't allow a blank either

Option spreads by definition have a short leg, so one number must be negative. For Wash Sales a 0 is returned in the field from my downloaded 1099, but Turbo Tax won't allow it, no will it be allowed if I delete the 0. How to fix both of these issues.
