Business expenses section on the tax page for the self-employed qb. Only $26, 2 of my very first transactions are showing up categorized.

Good day to you, @rdaletto.

You'll want to ensure you've categorized all your transactions for it to show in your Business expenses section. Let me guide you how.

1. Go to the Transactions menu.
2. Find a transaction on the list.
3. Select Business if the transaction was for business, or select Personal for personal. If the transaction was both, select Split.
4. Review the category in the Category column. 
5. If you need to change the category, select the category link. 
6. Select a general type, and choose a more detailed category.
7. Click Save once done.
