The IRS just released Schedule D for 2023 today (Dec. 21). They still have not released the Schedule D instructions or Form 8949 and its instructions for 2023. Those forms are needed to report stock sales. When the forms aren't available from the IRS, there's not much that TurboTax can do.
If you are using the CD/Download TurboTax software you can enter stock sales in forms mode (with the understanding, of course, that the forms aren't final).
