@Natasha-2907 Welcome to using Concur. It is likely that your company has an expense type named Ground Transportation, Public Transportation or something similar. You would use that expense type on your report. You will see certain fields marked with red. Those are required fields. Since you are new to using Concur, you might find this resource page helpful for you: https://www.concurtraining.com/toolkit/en/expense/end-user. You will see a list of expense related topics here along with helpful guides and short demonstration videos. Give these resources a look. I think you will find them very helpful for you as a new user.
