Unfortunately I can't do teamviewer or any live sessions, I'm sorry.
If you are trying to exclude custom post types based on taxonomy terms, then please check this section in the documentation:
– Excluding & Including results
– Excluding by taxonomy terms
– Including based on taxonomy terms
I believe this is what you are looking for. If you also want to exclude items that does not belong to any of the categories, make sure to turn off this option as well. This is also explained in the documentation links above.
If you however displaying individual taxonomy terms as results (not post types), but want to exclude some of them, you can do it on the General Options -> Sources 2 panel, by entering their IDs: https://i.imgur.com/JaStKXD.pngBest,
