Assuming that is in your HTML like this;
<style>@media only screen and (max-width :1050px) and (min-width :651px)
.tt_2cl,.tt_3cl,.tt_4cl,.tt_5cl,.tt_6cl
width:45%;margin:2.5%</style>
then excluding with tt_ works (well, it worked for me).
If that this CSS is inside a CSS-file, then you have to exclude based on the filename instead, so maybe that’s the problem?

OK I tried to exclude the whole plugin
/testimonials-showcase/
That doesn’t seem to work?
There are many dir/files uder the plugin folder
I mean
testimonials-showcase/,jquery-ui/
if you have /wp-content/plugins/testimonials-showcase/, then yes excluding using testimonials-showcase/ should work perfectly funsail ..
