if you are going to be due a refund, I would WAIT and not file until you have everything. That avoids the amendment headache.
if you think you will owe, I would go to the IRS website and make a payment tonight. Make the payment high enough so you are due a refund once you file. Then I wouild hold off filing until I had all my documents (why don't you ahve them all????)
there is no penalty for late filing if you are due a refund.
there are penalties if you owe and if you owe, there are late filing penalties as well.
