The first thing to look at is the PD7A report for the quarter. You will only use the Gross Payroll amount from the report. If you pay WCB for non-payroll subcontractors, you will also need a report for sub-contract payments for the quarter. That will be your Assessable Earnings amount.

Next, use the Pay Liabilities function in QB, enter the date parameters, select WCB and click the Review tab to review the cheque details. Don't File it yet.

Next, File the return on the Worksafe website (I use Fast File & Pay). When you enter the details, WCB premium is calculated for you. File the return on the Website. Print the return.

Compare the numbers to the Liability cheque. If they are not identical, use the adjust Liability function in QB and adjust the balance in QB to exactly match the WCB Return. When the Liability Cheque amount is the same as the Balance owing on the Worksafe Return, File the return in QB.
