After you file

Yes, you can amend your state return. Your federal return does not change based on your state residency, so unless you need to change your income or deductions, you can amend the state only.

I am assuming you are on active duty in the military since you said you were stationed in New York.

When you are in the military and are stationed in a different state, you file your taxes as a resident of your home of record state. If you have only military income, you don't have to file in the state where you are stationed.

If you have non-military income where you are stationed, such as a part time job, a spouse with a non-military job or a side business, that non-military income is taxable where you are stationed.
