Many thanks to TaxGuyBill and others that responded to my NOL carryforward question.  The link gives the official IRS explanation for documentation required for carryforwards.  George4Tacks also clarified that the first page of the 1045 called "Application for Tentative Refund" is only used for a carryback situation that would result in a refund.  I am using the other pages of the 1045, Schedule A & B, to manually calculate and document the carryforward.
