Hi Karen,
This is done through the Transactions menu > Transaction Entry screen. Select type Receivable Charge in the top left. Ensure the date is the last day of your previous fiscal year. Enter the description. Enter the amount of the refund in the Total field. Select A- (asset sale) instead of IN for the line type. Select account 1298 (or GST paid) from the account list. Analyst should automatically fill in the amount box to balance the entry. Press record. You'll get warnings essentially stating that these amounts will be omitted from the current years future return and you can just continue on. Let me know if you have any more questions. :)
