DHCP relay (ip helper-address) must be configured on the interface that receives the DHCP client broadcasts, which is GigabitEthernet0/1 in the 172.20.1.0/24 network. The helper address must point to the actual DHCP server IP, 172.20.255.11. Therefore, the correct configuration is interface GigabitEthernet0/1 with ip helper-address 172.20.255.11.
