I have been entering my deductions and the amount owed usually goes down after each entry. This is not happening this year? What is wrong?

For 2018, the standard deduction amounts increased significantly.  Once income is entered into TurboTax, the standard deduction amount is immediately applied to the return.  Therefore, when entering itemized deductions (mortgage interest, real estate taxes, medical expenses, charitable contributions), the total of the itemized amounts must be greater than the standard deduction before you will see any impact on your return.  And because the standard deduction amounts are higher, many taxpayers may not see any impact from entering itemized deductions for 2018.  See the 2018 standard deduction amounts below:
