According to Detlef Kremer’s E.T.A. Hoffmann: Leben, Werk, Wirkung (Walter de Gruyter, 2009, page 427) there are actually 5 piano sonatas by ETA Hoffmann, in A, F minor, F major, F minor and C♯ minor, AV nos. 22, 27, 29, 30 and 40, composed 1805 to 1808. A Joseph Elsner-edited publication of the A major was published in the same year of its composition (1805); this may however be the first publication of the other four. - Schissel
(Since this page is called "Piano Sonatas" one wants, of course, to round it out with the A major :) )
