I have a question about ev credit for 2023. If my tax liability line 24 is over 20k and I file jointly with spouse do I qualify for the ev credit

What I get confused about is the amount withheld already from our paychecks.  Usually what's withheld already from w2 is around 19k which means at the end of the year I owe around 1k.  Does this mean I can only get 1k of the $7,500  and lose out on $6,500 or I am looking to get 6,500 back because I already paid 19k in taxes ?? Please help
