@bellesellsde Thought id let you know and update that on day 10 after faxing I got confirmation from IRS (I called number with extension from letter) and they said they did receive my fax finally. He also gave me a date that I would receive refund of April 9th which would be "6 weeks from when I faxed" but it could be sooner. So I would definitely call on day 10 to see if they received yours.
