Are you doing a pass through of the credit? You should not be doing an override. The number should flow from the K-1.

If you are doing a return for someone who purchased a new vehicle, you have the wrong form. 

What is the right Form for someone who purchased a vehicle (not a pass-thru credit)?

I started to google:

Form 8834

and it filled in the rest: vs 8936

And it gives great results, including:

Unfortunately, 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.

That's the ticket - thank you SO much!
