Schedule A, Line 18 checkbox

Itemized deductions on Schedule A exceed the taxpayer standard deduction by approximately $6,000.  However, the Line 18 checkbox on Schedule A is checked by TurboTax indicating that itemized deductions have been selected even though less than the standard deduction.  Clearly this is incorrect and the checkbox should be left blank.

 

I am unable to remove this checkbox "check" through either the TurboTax interview process or an override.  I would appreciate guidance on how to remove it.

 

Thank you.
