If you've declared an invoice value in your August 2020 GSTR-3B but failed to upload it in your GSTR-1, you've encountered a common issue. The good news is that since the tax was already paid in GSTR-3B, you generally won't need to pay interest. You can typically report the missing invoice in your September 2020 GSTR-1 filing.
