Can I put 0 or less on line 11? I keep getting an error that reads "1040/1040sr Wks" Line 11 too large", although the calculation using the tool is a negative number.

This is for form 1040/1040SR. My tax liability for self-employment is less than the parameters that are set. The minimum value is 0, and the calculation is negative. Can I possibly remove this form all together?
