Huge number owed DC taxes

I am filing my 2022 tax return. I work for the government and my W2 says DE, Delaware for whatever reason. I live in DC and have already paid 2830 out of wages into state taxes. After completing my turbo tax forms, it says I still owe 2750. I’m in the tax bracket that should be paying 3500 in state taxes, it makes no sense to me why I’d have to pay over 5000. Did I do something wrong?
