Thanks for reaching out to us here today, @daniel623856.
I'll share the steps on how you can edit the mileage. There's isn't a product or services list in QuickBooks Self-Employed. You'll have to manually edit the mileage info from the invoice itself. Let me guide you how.
- Go to the Invoices tab.
- Locate the invoice, and then edit the mileage info.
- Click Save invoice.
For more details about invoices, check out this guide: Create invoices in QuickBooks Self-Employed.
On the other and, you can send feedback suggestions to let our engineers know about this feature. Just go to Assistant, type "send feedback" up until you'll see the button to click Give Feedback. See the image below.
Additionally, here are the links that'll guide you with mileage tracking and QuickBooks Self-Employed-related tasks. It has articles, topics, and detailed steps to track your business miles.
Please don't hesitate to reply if you have follow-up questions or concerns with mileage tracking. I'll be around for you. Take care and have a good one.
