I would suggest you contact the financial aid department…have them go through your aid application and see if they will explain why there is such a difference between the NPC and your actual aid.
But I do have one question…is there any chance your parents did a retirement rollover in 2019? If they did and you used the data retrieval tool, unless you indicated so, the rollover was included as income.
Also, check your financial aid application forms and make sure there are no errors on them.
