Not necessarily. Whether you need to amend or not depends on if the 1098 will be beneficial to your tax situation and if you chose to itemize your deductions. Form 1098 Mortgage Interest Statement reports the interest that you paid during the year and is deductible as an itemized deduction on Schedule A.
If you originally filed your return using your standard deduction- which is based on your filing status (as shown below), then you did not itemize your deductions or use Schedule A. Itemizing your deductions may be beneficial if the total of your itemized deductions exceed your standard deduction. If adding the 1098 increases your itemized deductions or if adding it allows your itemized deductions to exceed the standard deduction you were already given, you may want to amend your return.
You can find out if you used the standard or itemized deduction by reviewing your printed form 1040 line 40 or if you have a 1040ez or 1040a you used the standard deduction. TurboTax will also inform you while completing your return if you used the standard or itemized deduction.
See link below that explains how to amend your return using TurboTax.
