They're stored in the .idea/workspace.xml file, not as easily accessible as the lein one sorry. You'll see something like the following:
e.g.: cursive-1693/.idea/workspace.xml
<component name="ReplState" timestamp="1493686815183">{:repl-history {:ide [], :local [{:command "(def x 5)", :offset 9, :ns "cursive-1693.core"} {:command "(ns cursive-1693.core)", :offset 22, :ns "cursive-1693.core"} {:command "(defn foo\n \"I don't do a whole lot.\"\n [x]\n (println x \"Hello, World!\"))", :offset 74, :ns "cursive-1693.core"}], :remote []}}</component>
