Where do I enter IRS Form 8936 to my current 2023 tax return to receive my $3,750 Ford Mustang Mach-E EV tax deduction?

You will find the section for electric vehicle tax credits under Federal > Deductions & Credits > Cars and Other Things You Own > Energy-Efficient Vehicles.

You can also use the following steps to go to that section:

• On the TurboTax online screen, choose Help to open a search box (or for CD/downloaded TurboTax locate the search box in the upper right corner) 
• This opens a box where you can type in “energy efficient vehicle” (be sure to enter exactly as shown here)  
• The search results will give you an option to “Jump to energy efficient vehicle”
• Click on the blue “Jump to energy efficient vehicle” link and enter your information

The Giant BUT to that...

...is that the form 8936 is not scheduled to be final in the tax software until AFTER 21 February (and date could change)

SO you may need to wait until the 22nd of Feb to come back and go thru your entries again...the questions that need answering, and selections allowed, may change, requiring you to re-answer some, or change some of them.
