It is not unusual for form 763 ADJ not to be generated. 763ADJ has nothing to to with nonresident allocation of income. It has to do with adjustment to federal income, for VA reporting. The most common adjustments being the add back of federally tax exempt interest/dividends and the deduction for interest on federal bonds.
The allocation of your VA vs. non VA income shows on the bottom of page 2 of form 763 (non resident income tax form)
