Error Flagged Field that is correct and I can't correct

2017 TurboTax Deluxe - Form 1040 - Additional Other Taxes Smart Worksheet - Line E   Accumulation distribution of trusts: this entry is flagged as needing correction (contains "0") which is correct as I have NO trusts. When I try to do anything to change/override the value, nothing happens and the flag (pink field) remains. I have researched the issue inside and outside of TurboTax and not found how to clear this error ... please HELP
