I filed 2016 taxes through an accountant because there was an issue that couldn't be fixed when I tried to file on Turbotax. How do I erase 2016 from my Return Manager?

Click on the small blue trash can next to the return you want to delete. If there is no trash can, create a Standard new return, leave it blank but click on the "Save" button. When you go back to the Return Manager, you should now be able to delete your tax return, leaving only the blank one in the account.
