Is it better to fax or mail the additional information the irs has requested from me regarding my return as far as speed and efficiency?

They wanted my 1095A, a newly filled out and signed page 2 of my return, and a completed 8962 form. I have completed all of the above and am ready to send. Just want to know most efficient method to ensure my return is fixed and released to me ASAP. I needed that money to move and am now being evicted... Please help..
