We purchased a van for delivery services for our business. Where would I put this information and how?

You can create an asset for the new van. 

In order to add a new vehicle, here are the steps:

1. Navigate to Federal > Wages & Income > Self-employment income and expenses
2. Edit your business 
3. Choose add expenses for this work
4. Select Vehicle and continue
5. Now, vehicle will appear in list of expenses. Choose pencil icon to the right of vehicle expenses
6. Add vehicle for the new van (make sure to select the correct type based on weight)
