Ugh, sooo close to getting this one. OK, so I've been able to successfully complete step 1 (which by the way 4. Aliases I has to be correct, my guess, to get Aliases II right).
Step 1: nano ~/.bash_profile
Step 2: I typed in, beneath other aliases: export USER="Jane Doe"
2B: I don't use my own name
2C: I hit 'Control + O'
2D: I hit 'Enter'
2D: I hit 'Control + X'
2E: I type: clear
Step 3: Type in: source ~/.bash_profile
Step 4: Type in: echo $USER
I cannot get past this step and it's annoying me. Any help is much appreciated!
