QuickBooks saves your additions to the spell checker in a file UserDictionary.tlx. Note: There are several files with the same name and extension. Searching for UserDictionary.tlx may not find the one you need.
Your UserDictionary.tlx file (and the spell.ini file) are included when you make a local backup of your data file.
Your UserDictionary.tlx file is located in your program folder:
