Form 8936 and the related one for Schedule A are currently projected to become available on February 21, 2024.
As @DoninGA noted, many forms are still in process. This is primarily due to late changes in the tax laws from Congress and state legislatures, and then to policies, regulations, and forms as developed by the IRS and the state tax agencies. TurboTax and other software providers then have to reprogram and test their products.
