Welcome to the QuickBooks Community, @metallicoatd-gma. Let me share some ideas about assigning receipts to a project in QuickBooks.
Setting up and creating projects is available for QuickBooks Online Plus, Advanced, and Accountant. Though, assigning a receipt to a project is unavailable.
For now, you can use Tags in your QBSE account as a workaround. These are customizable labels that you can assign to your transactions and allow you to track your money any way you want.
To turn on this feature, please follow the steps below:
- Go to the Gear ⚙icon and select Manage Tags.
- Select the New ▼ dropdown and click Create new tag.
- Give the group a name.
- Select a color from the ▼ dropdown.
- Select Save.


Then, after you categorized your downloaded or manually entered transactions, you'll have the option to add tags to them. Let me show you how.
- Go to the Transactions menu.
- Choose the transactions you want to add the tags.
- Upload or drag the receipts.
- Click the Tags column and select the created tags.
- Hit Save.

To put them on the correct line of your Schedule C form, you can refer to this article For the step-by-step guide: Categorize transactions in QuickBooks Self-Employed.
If you wish to assign the receipt to a project, you may consider upgrading to QuickBooks Online. Then, you can start moving your QuickBooks Self-Employed data to QBO. Please check this reference for the detailed steps: Switch from QBSE to QuickBooks Online.
