When I enter my mortgage interest and property taxes, it does not change my refund. Is my interest not deductible? We are well under the $750,000 qualifying amount.

Yes, you are entitled to the mortgage interest deduction.  However, if your total itemized deductions including the mortgage interest and property tax on Schedule A are not greater than your standard deductions, you will not benefit from them. Note that with the new tax reform, TCJA, the new standard deductions have also nearly doubled from the previous amounts as well. (See below) As you are given a larger amount of standard deductions, it is harder for most of the taxpayers this year to take the itemized deductions. 

The amount of your standard deduction depends on the filing status you qualify for. In 2019 for example, single taxpayers and married taxpayers who file separate returns can claim a $12,200 standard deduction. Married couples filing jointly can claim an amount that's twice as large, $24,400, and taxpayers filing as "head of household" (single individuals with dependents) can claim a standard deduction of $18,350.
