A non-dividend distribution (also sometimes called a non-taxable distribution) should be entered as a return of capital.
This sort of transaction will very often not show up until the end of the year when a security reclassifies some or all of the dividends that they issued during the year.
If your club uses the online accounting at myICLUB.com you can use the add another type link to add one or more other types of dividend (return of capital, or capital gain) to an existing transaction, as described in FAQ 1090, at:https://www.iclub.com/faq/index.php?solution_id=1090
If your club uses the desktop Club Accounting 3, you will need to edit the original dividend, and also make separate entries for any part of the dividend that has been reclassified, so that the club still ends up with the correct amount of money.
