As you can see in the screenshot, I have an unneeded newline character in my prompt. Anyone know how to do remove this character from my prompt?

This "new line character" is part of your Bash prompt, kept in the $PS1 variable:
PS1='\[\e]0;\w\a\]\n\[\e[32m\]\u@\h \[\e[33m\]\w\[\e[0m\] \$ '
Remove it and put the updated PS1 in your ~/.bashrc.
See Customizing bash prompt for further information.

The thing is that the questioner knows the answer to the question as it is asked. Xe stated it in this almost identical question that xe asked three hours earlier.

@KitHo: Your prompt is printed when you press "Enter". That's where the new-line character is coming from. What is the output of
echo "$PS1"? Incidentally, your screenshot is difficult to read; I had to download a copy of the image to see the extra empty lines clearly. A textual copy-and-paste would have demonstrated the problem more clearly. – Keith Thompson – 2012-01-19T00:55:42.183
