What does it mean to allocate federal adjustments?

It's telling me because I was a nonresident of a particular state for part of the year, I have to allocate federal adjustments. What does this mean?

A Federal adjustment on a return could be a student loan deduction or a IRA deduction, or a number of other items.

So the Federal return has an adjustment to income on it, and the non-resident state return needs to know if that adjustment also applies to that state return.

Many times on a non-resident return the adjustment does not apply to the non-resident return.
