Setting static IP for Centos 8 laptop

I have a laptop with both a wired and wireless nic running Centos 8 server w/ gui. I wish to be able to access it via puTTY from the local network, and don't want its IP to change.

While I would rather use the wired connection, I first tried to edit the wireless connection using "sudo nmtui-edit wlp0s20f3", but received message "nmtui-edit: no such connection 'wlp0s20f3'"

I then tried the wired connection using "sudo nmtui-edit virbr0", and edited it as follows, but it doesn't appear to be working and ifconfing and ip route still show it as 192.X.
Code:IP4 CONFIGURATION <manual>
Addresses 10.120.11.40/24
Gateway 10.120.11.1
DNS servers 1.1.1.1
10.120.11.1How should I set up virbr0 to use a static 10.120.11.40. IP? Thank you
