I'm using the PC version, not the on-line version, so there's no left-side menu, and the "Tools" drop-down entry in the black "banner" at the top does not contain a "Delete a form" option.
However, I went into the "Tell Us About Your Schedules K-1" page, where I had used the "Partnerships/LLCs (Form 1065)" button instead of the "Estates or Trusts" button. I deleted the partnership version in the "Partnerships..." section and went into the "Estates or Trusts" path, and sure enough, there was the form, filled in with last year's Trust info. Thanks for your help!
