I need help adding a vendor to my account to calculate my income as best as possible

Hi joedstevens@hotm,

The QuickBooks Self-Employed is designed for small businesses. That being said, we're unable to add a vendor.

However, we can add and categorize their transactions .Here's how:

1. Click the Transactions tab.
2. Select Add transaction.
3. Enter a description of the TRANSACTION and AMOUNT.
4. Click the Select a category hyperlink.
5. Select an account.
6. Click Save.

    

I've also added this article as your guide when categorizing transactions: Categorize Transactions in QuickBooks Self-Employed.

I'm just around if there's anything that I can help. Keep safe!
