In the new 2020 ProSeries, the 1120S federal extension gets its own line in the e-file homebase, separate from the federal tax return itself. I had a few that were rejected and we mailed paper extensions. How can I remove this rejected extension from my e-file homebase? The tax return has since been e-filed successfully. I've tried unmarking the extension for efile and deleting the 7004 altogether, but it's still there.
