Form 8829 line 10 standard deduction problem

Hello all,

 

My wife has an at-home business for which we take the home office deduction.  I noticed a problem with Form 8829 that I cannot resolve.  TurboTax Home Business (desktop version) is putting the mortgage interest and mortgage insurance on line 10 even though we are taking the standard deduction.  I happened to read the IRS instructions for Form 8829, and it explicitly states that if you are taking the standard deduction, DO NOT put mortgage interest and insurance on line 10, nor real estate taxes on line 11.  But that is what TurboTax is doing!  Help!
