an error for multiple Liquid Crystal libraries were found
That's not an error. It's just some helpful information. You probably need to scroll up to see the actual error.

I only have one installed.
Clearly you have two installed. C:\Program Files (x86)\Arduino\libraries\LiquidCrystal is the version of the library that comes with the Arduino IDE. C:\Users\bmartinez19\Documents\Arduino\libraries\LiquidCrystal is the version of the library you installed, which overrides the version that comes with the Arduino IDE.
When you encounter an error you'll see a button on the right side of the orange bar "Copy error messages". Click that button. Paste the error in a message here USING CODE TAGS (</> button on the toolbar).
