the 8801 is the calculation of the allowable AMT carryover. some years ago Turbotax messed up on the calculation making the amount shown as a carryover way too high. this may be your situation. The IRS did not do anything about the incorrect carryforwards until recently even though the carryover has been wrong for years. OPs have had this issue too for the reason stated above
you do realize this is a public forum and identity thieves would like nothing better than to get a copy of your return.
your options
1) pay the bill
2) contact a tax pro to review your returns, they may require returns going back years
3) use the Audit Defense service provided by TaxResources, Inc., also called TaxAudit.com, in partnership with TurboTax. If you paid for Audit Defense and you received a notice, call TaxResources, Inc. at 877-829-9695, or report your notice on their website at http://intuit.taxaudit.com/. Do not contact the tax agency until you have spoken to TaxResources. They may contact them on your behalf.
