I assume that you have a little misunderstanding how VLANs work in the Meraki world. It would be good if you show a diagram of your topology.
First you need to distinguish between the ports and switches that connect a device that is member of a specific VLAN and the device that routes the van subnet to other subnets. Th later is what is shown on "Routing & DHCP". This routing can be done on a cap le L3 switch or on the Meraki MX. If you don't have the "Security & SD-WAN" element, you likely don't have an MX in your setup.
The routing needs to be done exactly on one device in your network This needs to be configured. But then you can use the VLANs on the Port-Settings wherever you need and the VLAN is trunked to.
Well, with a diagram it would be easier to give some better advice.
