It may be possible for you to file amended returns going back 10 years to change your sole prop to a QJV, because it will not result in a refund, it will only change to whom the taxes were assigned.....
Sorry, but it is not possible to file amended returns to change the sole proprietorship to a QJV on the facts stated; since @FrankinFlorida's wife did not materially participate in the business during those past tax years, a QJV election would not be allowed.
As an aside, an 1120-S is not a partnership return, it is the form used by S corporations (and also entities, including LLCs, that elect to be treated as S corporations for federal income tax purposes). Partnerships and multi-member LLCs (which default to partnership status) file Form 1065.
