A test tax return using the TurboTax 2023 Premier desktop edition for Windows gives the greater Itemized Deduction from Schedule A Line 17 of $31,976 versus the Standard Deduction for Married Filing Jointly with both spouses age 65 or older of $30,700 on the Form 1040 Line 12.
There is no problem with the TurboTax program giving the larger Itemized Deduction.
For some reason you have declined to look at the Schedule A of your 2023 federal tax return to see the amount shown on Line 17 of the Schedule.
