You may report your tax credit carryforward from Form 8801 under Deductions & Credits >> Estimates and Other Taxes Paid >> Credit for AMT Paid in Prior Year

Or open your return and go to the Search box at the top right side of the TurboTax header. Type in "8801", hit Enter, and click on  "jump to 8801" to go directly to beginning of this topic.
