The highest inclination human spaceflight I have found is Voskhod 2 at 64.8 degrees. Soyuz 22 and Voskhod 1 were close (64.75 and 64.7 degrees respectively). So none were ever retrograde.
(I thought the Soviet military Almaz stations had higher inclinations but it appears the manned ones were at 51.6 degrees. My searching of Russian space history is not optimum, so I easily might have missed something.)
Update: See also https://space.stackexchange.com/a/58208/6944 for a possible higher inclination that I missed (Vostok 6, 65.09 degrees) but sources vary on the value of the inclination. Still not retrograde.
