If you are not self-employed, the only thing you might need to enter about buying a new car is information if the car is an EV, or sales tax you paid if you are trying to itemize deductions.
SALES TAX
You can enter the sales tax you paid for the car you purchased in 2024 by going to
Federal>Deductions and Credits>Estimates and Other Taxes Paid> Sales Tax.
You will be asked if you paid sales tax on a major purchase, and you will be able to enter the sales tax you paid for your new vehicle.
Sales tax is an itemized deduction. Unless you have enough other itemized deductions to exceed your standard deduction the sales tax will have no effect on your tax due or refund.

Motor Vehicles (cars, trucks, motor homes, RV’s, sport utility vehicles and off-road vehicles
Aircraft or boats
Mobile homes
Manufactured housing
Building materials for major home improvements
