Check From Fiscal Office

So... Got my State weeks ago in my DD account. 

Had to identify who I was with federal (maybe because of the amount and claiming my son for the first time in over 6 years) and in my informed delivery I have a check from the Fiscal Office coming. I called the offset number and was told I do NOT owe anyone anything so not too sure why I'm getting a paper check today... And my efile status says my federal is processing but keep in mind it's been since January 24th. I'm very confused and any help would be appreciated!
