If you had sales of $60,000 and your total for refund checks and credit memos was $1000, the tax summary report shows only the total of the two amounts:
Gross receipts or sales 59,000
The QuickZoom report shows how the total breaks down:
Debit Credit Amount
1,000 60,000 59,000
In this case, the amount to report for gross sales is $60,000, not $59,000 as shown on the tax summary report.
