Why didn't my federal tax due decrease after I entered all of my deductions? The tax due is the same amount since I entered income & expenses and then all my deductions

If you are referring to deductions such as your mortgage interest and charitable contributions, then you probably are not exceeding the standard deduction for your filing status.

The recent tax law changes significantly increased the standard deduction amounts and it is more difficult to exceed the standard deduction for 2018. 

Take a look at the information below to learn more about the changes and to see some information about how to switch from the standard deduction to itemized deductions in your return so that you can see the difference.
