Does it mean I should not change the IP address? 192.168.1.199? my IP address is 192.168.1.100

no, that already commented, you can delete the static ip setting, just use by DHCP.

A16 does not retain State, when power goes off, it returns to Off State even if it is On state before pwoer goes off. 
I used ESPhome to flash A16

[admin]

there is "restore_mode" option for ESPHome.
RESTORE_DEFAULT_OFF - Attempt to restore state and default to OFF if not possible to restore.

here is detail: https://esphome.io/components/switch/

After adding the above lines in the YAML file, the board cannot flash, always displaying an error.

you can try to change option.
