You obviously didn't look at similar questions:
Would I get eligible for the the Plug in Electric car tax credit - TurboTax Support
As you see, s/he was getting $2k back, and due to the EV credit, is not getting $9,500 back. I'll do the math, since I know sometimes it's hard. $2,000 + $7,500 (EV credit) = $9,500 refund.
The ... that I left out intentionally, is a case where the person had less than $7,500 in tax liability (not withholdings), then they are not eligible for the full $7,500. Only up to what their tax liability is.
Liability = what you owe the government. The tax credit is based on this.
Withholdings = what you pay monthly/quarterly to offset your April tax bill
I hope this clears it up.
I have no idea what you mean by this, are you trying to insult me or are you bragging that you work for Toyota?
