Why is the refund so little?
Because you worked in Utah.
You were probably expecting to get it all back. That's not the way it works. You pay Utah tax on your Utah source income and file a non resident return. Then you report ALL your income on your WY resident return and calculate tax on it all, including the UT income. Then WY gives you a credit (or partial credit) for what you paid UT; so that you are not double taxed.
It works this way in almost all states.
