Can you attach supporting documents (like receipt and invoices) to transactions in QuickBooks Self-Employed? If not, which version of QuickBooks allows you to do that?

I'll provide additional details about attaching the receipt in QuickBooks Online (QBO) Solopreneur, Accounts.

In QBO Solopreneur, the option to attach a receipt on a transaction on the Transactions page is unavailable. You can only add attachments to invoices and estimates. Here's how:

1. Navigate to the +New menu.
2. Next, choose either Invoice or Estimate.
3. Once opened, scroll down to the Attachments section, and add the receipt or file you want. 

To know more about the features available for QBO Solopreneur, feel free to check this article: Introduction to QuickBooks Solopreneur.

If you want to add receipts like the one outlined by my colleague above, you might consider upgrading to a higher version of QBO (Simple Start, Essentials, Plus, and Advanced). 

Moreover, here's a resource you can use as a guide in managing your transaction for filing self-employed taxes: Schedule C and expense categories in QuickBooks Solopreneur and QuickBooks Self-Employed.
