In talking with Turbotax advisors (one of their tax advisors, who also drew in a higher level tech person) I discovered that a flaw in the programming is that if you answer the question of whether you received the credit from the dealer with "yes," the forms do not compute your credit right; in fact, the program will tell you that your credit is ZERO. This is a glitch in the system. I was instructed to answer the question with "NO" to obviate the problem, but this results in form 8936 wrongly stating that you did not receive the credit from the retailer. Turbotax needs to fix this. But in the meantime, if you do not mind filing by mail, you can correct the response on a hardcopy of 8936.
Hopefully someone from Turbotax sees this and effects the change.
