On a Mac it's in Users > "User name" > Library > Preferences > MAXON > Cinema 4D R20 > prefs. Or it can be found by opening Preferences in C4D (Edit menu, or Cmd + E) and clicking on the "Open Preferences Folder" button in the lower left corner (which also has the path displayed next to it). As always, make a backup of the original just in case.
I just copied and pasted the file in the prefs* path of R20 and it worked fined.
1 - I copied the Shortcuttable.res from C:\Users\PcName\AppData\Roaming\MAXON\Cinema 4D R19_BFE04C39\prefs
2 - I pasted the Shortcuttable.res in C:\Users\PcName\AppData\Roaming\MAXON\Cinema 4D R20_4FA5020E\prefs
*I noticed that there is no Shortcuttable file to overwrite in the R20 Path, I just Past it there anyway and worked fine.
