I found several LiquidCrystal I2C libraries which worked for this, but settled on the one here (v1.2.1). That version was recommended here.
Once the library is loaded, I loaded the example code "HelloWorld_i2c". There is only one parameter that I had to set from the example which is the I2C address which for my LCD is 0x27.

LiquidCrystal_I2C lcd(0x27); // Set the LCD I2C address
