"Form 8834 deals with another type of credit, and has a $2,500 max. The vehicle my client purchased is eligible for the $7,500 credit. Form 8936 is the only form I can find that deals with that credit level. Thank you anyway!"

What? We are trying to tell you that your original Title is the wrong form. You asked about 8834. You won't use 8834.

It's not unfortunate. It's a correction to your intent.
