Can someone provide input on how to properly input information for two leased vehicles used in the same year for self-employment reasons?

In the vehicles expenses section, you'll find two spots for information - vehicle A and vehicle B. The vehicle A information has been carried forward. Enter the additional information for that vehicle in the Vehicle A column. In the vehicle B column, enter the mileage and expenses for that vehicle alone.

In the Fixed Assets section of the expenses, you'll record the addition of the new vehicle and the disposal of the old one.
