After receiving " Reject Code FDI_8936_EVCredit_Er" I went into Turbotax to fix the return. It doesn't appear that Turbotax is calculating the code correctly. I was supposed to receive a $1795 credit but Turbotax only gave me $469 credit. How do you verify it is correct?
The fix for Form 8936 was included in the February 20th release. As insurance, delete Form 8936 and reenter it. It should go through then.
