How to take ITC of GST Paid on Reverse Charge?

I'm a registered supplier and I took GTA Services, and paid 5% tax on RCM basis. I took ITC in GSTR 3B of next month, but Which invoice details do I need to incorporate in GSTR 1 in order to avail ITC of tax paid? I need to fill Invoice details of GTA or I need to make my own Payment Voucher and fill in the Voucher number in GSTR 1? Please guide..
