I have the same issue with TT. I got rejected twice "Reject Code FDI_8936_EVCredit_Er". I am supposed to get $1875 for my model 3. Form 8936 line 4a shows $1875, line 4b shows 25% and 4c tentative credit shows $1875. I can't understand what went wrong. And the option to "fix the return" is not doing anything but filing with the same form.
