Can't itemize my deductions even though I believe I should be above standard deduction

I should be itemizing my deductions, I believe.  I have about a $685k mortgage that I refi-ed this year and paid about $25k in total interest.  I've entered them both in, with the one payoff date and it seems like it's not recognizing it and kicking me to the standard deduction.  I think I should be able to itemize about $35k with the $10k state/local tax deduction plus the $25k interest.  Am I doing something wrong?  I'm wondering if it's thinking I'm over the $750k limit.  Help!
