you could start a fresh thread in the community here with the specifics of your situation and see if the experts here can advise on the tax math. there are a lot of threads about win 10 and the readiness of turbotax, so the actual tax issues get buried in here.
I don't know enough about the EV credit situation and what changed in the big bill but I would think that's an area where using 2024 software may be tricky.
If forms mode or dinktytown don't work for you then others have reported using FreeTaxUSA or switched to HR Block to do estimates but I can't vouch for either option.
if you end up having to switch unfortunately, you can request refund on TT from Intuit here
