At this late date, you should file an extension (4868) by July 15th, estimating somehow how much tax you will owe, and then as soon as possible getting this information so that you can pay the correct amount of tax.
If you don't pay enough tax on your extension, then you will be paying interest on the unpaid tax until such time that you file your real return with the amount you owe.
But at least the paperwork will be in order (you filed in time).
