Sounds like you are indicating you want to 'Clear and Start Over' your entire return.
To delete just your State Return in TurboTax Online, in the left-side menu, click on State Taxes.
When your States are shown, click on the Garbage Can icon, as you said.
You should get a message 'If you delete your xxxx return, all of your data will be lost. Do you want to delete this return?'
Your choices will be Delete or Cancel.
