I've always known optifine doesn't go along modded minecraft
Because the most recent version of optifine available is for 47.1.43 and that's a review version, so no you cannot use optifine and forge for any version of forge after 47.1.43 and even if you do downgrade your forge to accommodate, some 1.20.1 mods are incompatible with it, i found that out trying forge 47.0.35 most good 1.20.1 mods like aether and twilight forest need 47.1 or higher to work.

Optifine is a tool available for java minecraft which provides more festures and better control of the graphics of the game and provides for the use of shader programs to change the visuals of the game Optifine offers many graphical improvements without using shaders but when using shaders the game can take on a whole new view.

As long as you downloaded from optifine.net, you're fine.
