How to calculate NC Sales & Use tax "Gross Receipts" using QBO Tax liability report? Would it be Gross Total less Tax Amount, Taxable amount less Tax Amount, etc.? - TIA

In NC, the 1st line item is "Gross Receipts", which is the total amount of gross receipts from your business operations that are sourced to the state. Do not include any sales and use taxes collected. You are not required to include gross receipts from real property contracts.

If you run the Monthly Sales Tax Liability Report on Quickbooks Online, you have the following columns: Gross Total, Non-taxable, Taxable Amount, and Tax Amount. How would you calculate the number to enter for Gross Receipts?  Would it be Gross Total less Tax Amount, Taxable amount less Tax Amount, etc.?
Thanks in advance!
