I have a government pension that I and my employer contributed to (457b).
Throughout my career my contributions were exempt form federal tax
I paid NJ state income taxes throughout my career
On the NJ form I could exclude the income from this past year that I already paid tax on.
I moved to Delaware fro 2020
The Delaware program is taxing me on the full amount of my pension payments, which have already been taxed by NJ.
How do I exclude the pension payments for this year's Delaware tax return?
