Here's how:
- Go to Transactions and select the dropdown next to New transaction.

- Click the Manage categories menu.
- Choose the appropriate expense type. In your case, Healthcare.

- Hit the Add category button to create a name and add a description.
- Once done, hit Save.
You can also edit, hide, or unhide categories. Check out this guide to learn more: Categorize bank transactions in QuickBooks Solopreneur.
