<prompt> Human: Today my wife opened and handed me a letter from the IRS saying i owe 355 and i need to enclose a check with IRS writen on it with my social number on it. It requested it to be sent to a PO Box address. Letter had bad looking barcodes.Why would i owe the IRS money? I filled with HR block. I had paid the amount that my accountant has determined, on time at the website.  <response>: It sounds like this may be a scam. See if this applies.
