So, I'm waiting for my tax return and instead of getting it I get a notice from the Department of Treasury stating that my refund is being used to pay a debt through Child Support Services.

Where do I even begin to contest a parenthood claim from 1500 miles away? The letter includes some basic information about Child Support Services and gives a contact number, but it would seem I've already been legally declared the father of some kid that isn't mine in a state that I haven't lived in for five years.

Does reddit have a clue where to start? After contacting the IRS and Child Support Services, where do I go to contest the claim of parenthood?

Help?
