It's good to have you here in the Intuit Community, Fia,

Let me get the help you need in creating your invoices in QuickBooks Self-Employed.

Here's what you'll need to do:

1. Go to Invoices from the left menu.
2. Click on Create invoice button at the upper right hand.
3. Enter the necessary information and make sure to enter the correct invoice date.
4. In the Description section, click on Add work link, then enter details of the invoice.
5. Click Add to invoice.
6. Click Send invoice.

For additional information, I'm attaching a helpful article that you can check: Easy invoicing in QuickBooks Self-Employed. 

That's it! You're now able to create invoices from April 17 - March 18.

Feel free to reach back out, if there's anything else you need help with in an creating invoice. I'd be happy to help.
