Hey there, alicewalton.
Thanks for dropping by the Community, I'm happy to shed some light on the exciting new Time feature in QuickBooks Self Employed. While you can't rename an existing project, you can switch to a different project. Considering the feature is still in Beta, I will recommend this change to our product development team to see if they can add it to the next version when it's updated.
Thank you for dropping by and have a lovely afternoon.
