Hello @thesrqpilot-gmai,
As of the moment, there isn't an integrated way to delete a project while working with your time entries. With this, I'd suggest sharing your request directly with our product developers by sending feedback. I'll show you how.
- Access the Assistant utility.

- Select I need help.

- On the Type something... text entry, enter Feedback.
- Press the Send button.

- Select Add a feature.

- Use your text box to enter a few words describing your request..

- When you're finished, hit Send.
- Click Yes.
Additionally, you can also check our resources page for the list of article you can use while doing business with us: Browse all Articles for your QuickBooks Product.
Don't hesitate to post again here if you have other questions or concerns with QuickBooks tasks and navigations. I'm always around happy to help. Take care and stay safe!
