I received IRS notice "Our records show you claimed too large of a Home Mortgage Interest Deduction on Schedule A of your 2024 Form 1040 tax return". What am I doing?

Filed with TurboTax and received this notice on 12/15: Our records show you claimed too large of a Home Mortgage Interest Deduction on Schedule A of your 2024 Form 1040 tax return. Review and fix any incorrect home mortgage interest claims. This may help you avoid additional interest or penalties. How do i review my return and determine if it's right or wrong? and what the rules for that deduction?
