Is Form 8936 Bugged? Can't figure out how to complete the form, got a letter saying I need to. (Filed already)

[JKV7]

We bought a used EV that qualified for the $4k credit per form 8936.  The credit was transferred to the dealership at the time of the purchase.  After we filed, however, we got a letter saying that we were "required to file Form 8936 and 8936 Schedule A."

Now, we did file both of these, but they look really incomplete.  

TurboTax will NOT prompt us to fill in anything past Line 13b -- it looks like I should be filling in a few of the boxes below that (d, e, f, etc.) and  - most importantly - it NEVER prompted us to put in a sale price!  It just assumed that the 4k would be automatically accepted.  On line 13b it does say, "If you transferred the credit amount to the dealer at the time of sale, stop here and see instructions."  But there are no directions.

Is this a bug?  Am I missing something?  Was the letter just a form letter that got to us after we filed?

Thanks for any help.

Can you clarify if you are having an issue with TurboTax not asking all the interview questions in the amendment process or was this when you originally filed your return?
