EV tax credit and hit by the IRS with $20k for no paying penalty and taxes on a 401k

HI all,

I owe the IRS 20k for an old (2021) 401k I cashed out before 65yo

I paid some taxes on the forms Fidelity sent but IRS told me that is not enough to cover al the taxes and penalties.

My tax advisor told me that if I get an EV with a $7.5k EV tax credit, I can use that credit and reduce what I owe to the IRS more than 1/3rd. Is this true? I cashed out the 401k on 2021 but i will purchasing the EV vehicle (that qualifies for the credit) in 2023.

If someone knows, please let me know

Thanks all!
