Mortgage interest and Taxes deduction

[edgarbiii]

My wife and her sister have a mortgage on a house.  They split the Interest and the taxes on their returns.  In the past there was a place where it said "If the amount you are deducting is different than what is on the 1098 please explain".  I would then explain that the two are splitting the deductions and would list the amount.  I can't find this on TurboTax this year.  Where do I explain this without the IRS sending me a letter to explain?

Thanks

The question is still there.  It is a check box directly under the Box 1 Mortgage Interest entry.  The label says "The interest amount I entered is different than what's on my 1098".
