The problem in in line 12 where the federal instructions say to enter $1,000 for each house in which that you installed EV charging. TurboTax does not tell you that you should enter something on line 12. However, if you click on the field you get a subform where you can enter one or more address and $1,000 for each address. This info then gets put in line 12 and becomes the Federal EV tax credit.
I look at this as a TurboTax bug for not letting you know that you need to enter something in line 12.
