You can’t delete the last return that you were working on. Please open another return in your account and then select “View All Tax Returns” to go back to delete the ReFile that you don’t want.
If you are using the TurboTax App, or TurboTax Online on a smaller screen, you will not see a trash can. Instead, there will be an option to delete under the return’s “Last Updated” information.
Please visit this TurboTax FAQ for more information: How do I delete a return in TurboTax Online?
Thank you for choosing TurboTax.
