This article traces the source of this particular long-time delusion / fabrication:

After Trump made the claim in 2019, Trott contacted CNN to note that at a roundtable event with automotive executives in 2017, Trump had suggested he received the “Man of the Year” award at a 2013 event in Michigan where Trott had invited him to give a speech, a Lincoln Day dinner Trott had chaired in Oakland County. At that event, Trott gave Trump a framed copy of Lincoln’s Gettysburg Address and other gifts. But Trott emphatically noted that he did not give Trump any “Man of the Year” award, nor did anyone else there.
