If your mortgage was serviced by two different servicers during the year, each will issue a Form 1098 showing only the mortgage interest paid to that servicer. That said, if you have enough mortgage interest, taxes, medical, and other deductions to make itemizing worthwhile, then I would urge you to amend your tax return to take advantage of this additional $3,000 of deductible interest.
TurboTax will guide you through correctly entering your new data
and printing Form 1040X. You may also have to amend your state income tax
return if you have a state income tax. Please note that amended tax
returns must be filed by mail.
For more information, please see TurboTax
Guide - Amending Your Income Tax Return.
