No homework

I received a notice from the IRS that I owe $1107 on my 2013 taxes filed last year. I’m sure it’s related wither to Unemployment compensation(where tax wasn’t withheld) or an IRA that I withdrew money from to survive. But I thought the IRA was already accounted for. 🙁
I *have* the money, thanks to my BEF…but CRAP…
