I just got the same error - and I am not even qualifying for the alternative fueling credit! We also installed solar this year and are getting a credit for that so we lose this credit because of the Tentative Min Tax threshold - but I still want t file now and get my refund. So I just deleted from 8911 from my filing - and it let me go through. I'll doublecheck when TT finally does the update to make sure I don't now qualify for some reason - in which case I'll amend my return.
