Hello there, @MIKER1.

I'd be glad to help you today so you'll be able to generate your Profit and Loss (P&L) report correctly.

To help us check why your P&L report shows Car, van and travel expenses as zero but has the correct figure on the Tax summary, is by checking the date range of the report you've opened. It's possible that the report's date isn't customized/filtered correctly.

To customize the report's date range:

1. On the report's page, click on the drop-down arrow beside the date selected.
2. Select the date range you want to include or customize the period you want to open.

You can see attached screenshots for additional reference.

For further details about car, van, and travel expenses, you can check this article: About car, van, and travel expenses.

Stay posted if you have any other questions about running reports in QuickBooks Self-Employed. I'll be always here to help you!
