How do I get my 2020 Profit and Loss detail?

I've got you covered, @eileenmedina47.

You can customize the reporting period of your Profit and Loss Detail report to show all your data from last year. Here's how:

1. In your QuickBooks Online (QBO), click Reports from the left menu.
2. Select the Profit and Loss Detail report under the Business Overview section.
3. On the report, select Last year from the Report period drop-down.
4. Click Run report to show the changes.
