In 2021, we purchased a Hybrid Pacifica which qualifies for the $7500 tax credit. How do you enter this in TurboTax?

It's a credit (subtraction from taxes due), not a deduction (subtraction from income, before taxes are calculated), and is reported on Form 8936.  I believe you access it here:

• Click on the Federal Income tab.
• Click on Deductions & Credits.
• Scroll down to Cars and Other Things You Own.
• Click Start/Edit/Update next to Energy-Efficient Vehicles.

To apply for the Plug-in Electric Drive Motor Vehicle Credit, you will follow the steps below once you are in your return:

• Click on Deductions and Credits
