Where do you see that TurboTax calculated itemized deductions of $29,650? On the summary screen "Your 2023 Deductions & Credits" it shows the amounts that you entered, without considering any limits that apply to the deductions. Look at the actual Schedule A, not a summary screen in TurboTax. What is the amount on Schedule A line 17? It's probably $24,799.
Here are some examples of the limits on itemized deductions.
- For medical expenses, only the amount in excess of 7.5% of your AGI can be deducted.
- The total deduction for state and local taxes is limited to a maximum of $10,000 ($5,000 if you are married filing separately). The maximum applies to the total of real estate tax, personal property tax, and either state and local income tax or state and local sales tax.
- The mortgage interest deduction might be limited depending on various factors, including the total balance of your mortgage debt.
- Donations to charity might be limited depending on the type of charity and the amount of your donations.
