The IRS is very specific about the documents that they need/want to verify a position you took on your tax return. Contact the IRS and have them explain what their exact expectations are. You can also ask the IRS what specific forms they want, or what documents are considered sufficient for examination/review purposes. I would contact the IRS as soon as you could to get this information. The IRS contact number is 800-829-1040.
