So I got an IRS Audit letter concerning my 2011 taxes and it's confusing to say the least. The main and only difference is the following 1099-INT they received supposedly.

#001 SNN: xxx-xx-xxx Form 1099-INT
Desc:
Sales Date: 05-23-2012
US DISTRICT COURT
1 COURTHOUSE WAY
SUITE 2300
BOSTON, MA 02210

Amount Reported to IRS: $45,107
Amount Included on Return: $0



My question is, does anyone know what the hell this thing could be? First off, it has a sales date of 2012, yet this is an issue they have with my 2011 taxes. Second, it's from the US District Court, for a sale? I have no idea what I could have done that would have the Mass US District Court paying me interest on a sale. And if it helps, that amount is pretty close to my overall income, so it's a significant amount for me if there's something owed to me that I never received or whatever this is.

It's late on a Friday and I just checked my mail so there's not really anyone to call, although I'm not even sure who I would call at the court house to ask about this, they don't have a finance dept and I wasn't their employee.

Anyway, any help would be appreciate so I'm not completely freaked out all weekend. Thank you.
