I checked all the wireless channels which my adapter supports.

I changed my settings to channel 13 since that is using only ht/20. Is that ok for further testing?

hi,
you can do that. but I'm surprised there's no way in pfsense to
explicitly configure the channel as being ht/20 only.
You may find some devices won't let you tune to channel 13. It's all
very regulatory-y restricted.
