So sorry to hear you are also having a problem with the EV charging station credit, but IMO it appears impossible to get help from turbotax. There seems to be nowhere to report a bug or problem with a form not working properly or not being updated properly. I have encountered this before and it is extremely irritating.
Despite two previous promised deadlines of updated 8911 form availability passing, it appears turbotax probably still has not updated the form so taxes can be filed through turbotax if you need to claim the credit since again trying to update earlier today and reprocess I also get $0 credit and I know I am eligible. All I can suggest is if you know for certain you are eligible, filing the "old fashioned paper mail" way using the IRS website forms, or filing now through turbotax w/o the credit and trying to do an amended return through turbotax later. (Note you may have to delay filing an amended return until your original return is processed; I have had to do this before due to problems with lack of timely updating by turbotax before and it is a hassle which unfortunately is likely unavoidable for those of us who do not want to wait weeks to months for our refunds.) Or of course it is an option to continue to wait for turbotax to get around to updating the form but who knows when that will be.
IMO best to carefully review the new additional eligibility requirements regarding geographic location; others have posted the link for that determination in this topic thread and the IRS website also contains a link to the census mapping system used fpo determining eligibility of the credit based on location under the Form 8911 section. Even if turbotax updates the forms, it is unknown if they will be updating software to automatically calculate eligibility based on installation location so IMO best to determine this yourself.
Good luck and sorry you are also experiencing this frustration.
