I downloaded & printed the form 8453 that TurboTax gave me but no where on it or anywhere else does it say what I must send with that form. None of the boxes are marked/checked. I talked to live support earlier & I was sent 2 links which didn't help me one bit. How do I find out what I need to send with the 8453 form within 3 days after the IRS accepts my return, which they did. Thank you, any help would be so grateful.
