1) Restart the Mac.
If the error persists then:
2) Use top menu bar File -> (hold Option key down) and Save As and save it to your User desktop.
You can check the lock status for files or Folders with the Finder -> Get Info).
You should review the the permissions on the default Documents Folder if that is where it was trying to save to. (There are many Mac or Apple discussion groups or articles for help with this. It is beyond the scope of a tax forum to troubleshoot a local Mac issue.)
