My audio seems a little muffled, and it’s really ticking me off 
Can someone tell me how to fix this? Thanks!!

You can start with the info in the pink band above and then flesh out your question a little using these hints:

Audacity 2.1.X is capable of real-time adjustment of effects.
If you are using windows there are free equalizer plug-ins where you can immediately hear the consequence of say boosting the treble to make the sound less muffled, see the ogg video here … https://forum.audacityteam.org/t/version-2-1-1-0-doesnt-remember-equalization/39205/5
