Yeah, maybe there's a bug. I would play around with income numbers to see if it affects which credits (and for how much) get applied. That's how I usually go about trying to understand these things. It might be a pain, but sometimes you could also check if you get the same numbers with another software.Maybe, but it doen't affect the EV credit at all or the Home Energy credits at all either. That is the reason I think it is particularly weird for it to only affect the charger credit (could just be a bug in the 8911 form in TurboTax).
