Sounds like you need a De-esser plugin …  
There are two free ones made specifically for Audacity …  
[Paul-L’s de-esser](https://forum.audacityteam.org/t/updated-de-clicker-and-new-de-esser-for-speech/34283/1) precise, but complex & can be slow.  
[Steve’s de-esser plugin](https://forum.audacityteam.org/t/please-help-with-de-sser/48588/14) less precise, but simple & fast.
