How do I delete a K-1 which TurboTax won't show me or let me delete & which contains no data because there are no data for it anywhere in my return?

TurboTax won't let me file my federal 1040 electronically because TurboTax insists that I have a K-1 which I do not have, nor have I entered any particulars because they do not exist.  Am I stuck with filing by mail, rather than electronically?  The state form is where the hang-up seems to exist.  But there's nothing to delete, no K-1, no underlying data.  Very frustrating.
