As ErnieS0 notes above, you don’t have to report your Form 1098 mortgage interest on your return.
But if it’ll help you qualify for itemized deductions, and especially if you claimed itemized deductions on your original return, you’d want to enter the data from the form into TurboTax.
In that event, an amendment would give you a tax benefit.
Please see the TurboTax Help article What's my standard deduction for 2021? to see the standard deduction amount you need to surpass to claim itemized deductions.
