Itemized deductions

To whom it may concern

I have entered 17,500 in charitable donations and Medical costs. In addition I have entered  12 K in real estate and mortgage interest I know there is now a limitation of 10 K for real estate taxes and interest

So Ii should have a itemized deductible total of 27,500 however turbo tax app is choosing standard deduction of 24,400, Is there an issue with app calculating itemized deductions. The app has not changed much since last year and I have entered my deductions in the same fashion as last year
