massive technological assistance early 20th century to ensure world socialism by the 1950s (and assuming this just creates a new alternate time line since i doubt you can go into the actual past). the exact logistics depend on the time machine. the exact date will be critical because just your appearance will start alternating the events you know so at that point it's a race. modern medicine, weapons tech, manufacturing techniques, possibly actual material (compact weapons, components, anything that you can boostrap from).
honestly if i was going to pick a singular event to bet my money on it would be to help the spartacist uprising to succeed. drop in a bit ahead of it, give rosa as much foresight as possible (warning her my very appearance could start altering it but i think it would allow a better game plan). provide them with advanced weapons, disassembled microfactories, body armor, communications gear, etc. M1A1 might suck for urban warfare i think assault weapons, body armor, and advanced training be best

Give Rosa an M1A1 tank.
