Additional form needed for adding a second vehicle for business in Turbo Tax

It depends on the type of business and what type of return you are preparing. In most cases, you will find a button to "Add Another Vehicle" under the current list of vehicles that have already been entered for your business. Follow the prompts from that selection to set up your second business vehicle.

The easiest way to find any section of TurboTax for Desktop is to open your return and use the Search box at the top right side of the TurboTax header. Click on the magnifying glass, type in the topic you need, hit Enter, and click the "jump to" link to go directly to beginning of that topic.

In TurboTax Online, go to Tax Tools in the left column >> Tools >> Topic Search. Type in your topic, click the topic in the list and then GO to go directly to the start of that section.
