How do I file married filing separately claiming the standard deduction, when TurboTax says my spouse is itemizing deductions (with no form filled out for her yet)?

I am trying to file married filing separately, taking the standard deduction, but when I get to the Deductions & Credits section, it says that since my spouse is itemizing deductions, I must also itemize deductions.  I haven't even filled out my wife's married filing separately form yet.  How does TurboTax assume that she will be itemizing deductions???  How do I override this so we can both file separately claiming the standard deduction?
