"and this was the second of two"
I wonder if this is their Second Page, because you cannot fit more than two States on that section, so someone issued it as page 2. That info is just Info; it isn't even used by the IRS.
For instance, that might be a local code for taxing earnings, such as City or Local code. Or, you stated AIMS? Some institutional program stipend?
"Level Up" is a gaming function, not a real life function.
