I am freelance technical consultant for research and development.  I am a registered GST client.  I gave an invoice to my customer in July and received payment at the end of July.  I submitted an invoice also to my client towards my technical service.  I have been submitting monthly GSTR3B for June, Jully, August and September months.  I filed the quarterly GSTR1 for the first quarter Apr-June which is nil.  I submitted GSTR1 for second quarter Jully-Sep yesterday but failed to upload the Invoice.  But the due taxes were paid through Epayment.  Now my question is 1.  should I upload the invoice since it is only for technical service and  may not qualify for any credit...2.  Can I correct my mistake and upload my inovice since there is time till the end of the month to file returns.  kindly help me....
