$7500 ev credit disappear after latest turbotax update? Tried to re-enter the information again but it doesn't have any effect even though it claims I'm qualified.

I entered my ev credit two weeks ago and it took 7500 off my tax due. However, after the latest turbotax update, the credit disappear so I tried to re-enter again, it said I'm qualified for the credit but now it doesn't change my tax due anymore.
