Why is my rent is not being reflected on my Profit and Loss statement despite being categorized correctly as a business expense?

I'll explain why the home office expense is excluded in the Profit and Loss statement, @starlaclearwater.

We use the simplified home office deduction in our calculations due to the category's calculation complexity. That's why expenses you tag with any home office expense account appear in the Tax Summary and Tax Details reports, not in Profit and Loss. Make sure to indicate the correct report period or tax year to see the amount on the Tax Summary/Tax Details report.

You can refer to this article for more details: Schedule C and expense categories in QuickBooks Self-Employed. You'll see a table with an expense categories list, along with an indicator if they appear in the Profit and Loss report or not when clicking the Learn how Schedule C categories appear on reports drop-down. 

Additionally, I suggest you reviewing this article to track home office expenses efficiently: Track home office deductions and enter square footage. While this article is for QuickBooks Solopreneur, it contains the same information on how we calculate home office expenses and the methods used in QBSE.
