Last year I had a Schedule K-1, but I don't this year. The software is carrying over the information. How do I delete that from this year's return

To remove an unneeded form:

1. Go to "My Account" in the menu bar

2. Choose "Tools"

3.  In the dialog that opens, choose "Delete a Form"

4. Click Delete next to the Schedule K-1 you need to remove.

Note its generally recommended not to delete forms unless you're sure its there by mistake.
