If firewall doing routing for your vlans. That may not be optimal as the switch can do it faster in hardware.

Hello,
1) You have duplicate IP addresses in your network. You've configured the switch to have IP addresses in vlan 10/20 that are on the firewall. If you want the firewall to route between the vlans, take the ip addresses off the switch (or change them to a different IP address)
This:
interface Vlan10
ip address 192.168.10.1 255.255.255.0
!
interface Vlan20
ip address 192.168.20.1 255.255.255.0
!
conflicts on the firewall with this:
ip address in_vlan10 192.168.10.1 255.255.255.0
ip address in_vlan20 192.168.20.1 255.255.255.0
Also, one of your static statements appears to be incorrect:
static (in_vlan20,outside) 192.168.1.99 192.168.10.2 netmask 255.255.255.255 0
192.168.10.2 doesn't exist on that vlan - this is vlan 20. It should read:
static (in_vlan20,outside) 192.168.1.99 192.168.20.2 netmask 255.255.255.255 0
Make sure you do a clear xlate before you try this all out.
