you're misinterpreting what's on the webpage. the credit is taken on the 2023 return. that's why Turbotax will not allow your entries.
The amount of the credit depends on when you placed the vehicle in service (took delivery), regardless of purchase date.
According to the instructions given by the IRS, a taxpayer a may not claim the credit before they take possession of the vehicle. If a taxpayer does not take physical of a qualified vehicle by December 31, 2022, the EV tax credit cannot be taken until tax year 2023.
