I recently noticed that I'd missed adding a significant expense that included GST from last October. Obviously the GST doesn't appear in the December BAS. When I start my March BAS I see:
"Your BAS report now includes late or edited transactions from past periods. The adjusted amounts are ready for you to review and send to the ATO."
However, when I proceed it shows only transactions from Jan-Mar, and doesn't included the missed one from October. What do I need to do to include it?
