Thanks for the advice, MonicaK1.
Yesterday, I went back in. Once again, TurboTax said I had one more step to finish, and once again showed a partial image of an unavailable tax form. However, the writing above indicated that this time, the form was 8911, which is a form to claim tax credit for EV charging property, a business credit. At that point I called customer support, and after the usual recorded options, and me insisting "agent", I got a wonderful agent who joined me on the computer and fixed it. Magically, I was then able to finish and file. My return is now in the friendly hands of the IRS and FTB.
This is a bad look for TurboTax. Apparently, form 8936 has been available for some time (as you said), but I was never notified. Why it substituted form 8911 is a mystery to me and the agent. He said he would bring these matters up to the next level, but who knows? He also kindly gave me a $30 credit for next year, but again, we'll see. For all the work and time I spent on this, I should be made a VP of Intuit.
Again, thanks for all the effort on this forum to help.
