Correct.
Mortgage interest is an itemized deduction, just like state/local taxes, medical expenses and property taxes. The total amount of your itemized deductions must exceed the standard deduction before you will notice a difference on your tax return,
With the increased in the standard deductions ($12,000 for single filers, $24,000 for married filers), fewer people are seeing the tax benefit of the mortgage interest.
You can still enter your mortgage under Deductions & Credits, but you may not see it on your return.
