VLAN Interface Question

Good morning,

I have a small network with two Cisco Catalyst 3650 switches connected together via fiber.

On switch1, I have configured three VLAN interfaces and VLANs as below:

interface vlan 20: 10.101.20.1/24

interface vlan 110: 10.101.110.1/24

interface vlan 200: 200.0.0.1/24

vlan 20 (Clients)

vlan 110 (Network Devices)

vlan 200 (Production Machines)

On switch 2, I have configured one VLAN interface and the three VLANs mentioned above.

interface vlan 110: 10.101.110.2/24

So I am at the testing phase, and am running into some issues. First, when I statically set a laptop up on the 20 VLAN (10.101.20.110/24) and plug into switch1, I can talk to devices on different vlans connected to the same switch. However from that laptop, I cannot ping 10.101.110.2 (I can ping it from switch1). Also, from switch2, I am unable to ping any of the default gateways (VLAN Interfaces) from switch1.

Any ideas or suggestions would be greatly appreciated. This is my first solo network config so I'm sure its just a stupid rookie mistake! I am here trying to better myself as a network admin, so please provide any constructive criticism you can :)!!!
