Deductions & credits

Are you sure this is correct? I’m undergoing an audit right now for tax year 2022. My Wife and I claimed a total of four EV tax credits that year. We are married filing jointly. All four cars happen to be in my name because I did not know there was a limit. They’re now claiming there is a two car limit per individual. Had I known that I simply would’ve put two in my name and two in her name.
