@Click That is odd you are seeing an incorrect Standard Deduction for 2023 using the What-If worksheet.
I am using the 2022 Premier edition for Windows version 022.000.0738 and on my worksheet for Column 2 with the 2023 tax rates selected it shows 30,700 for MFJ when both are age 65 or older.
If you are using Windows check your version. Click on Help at the top of the screen then click on About TurboTax and then the Version tab.
