The IRS clearly states in the instructions Part 1 is only for Estates and Trusts, I am an Individual filing 1040 not 1041. Past years in TurboTax, this Part 1has always been correctly blank, this is causing my excess AMT carryover to be drastically reduced.

Since Part 1 shouldn't be active for you, the software is likely "tripping" over a specific entry. Here is how to troubleshoot and force the correction:

Check the "Form 8801 Worksheet" in Forms Mode: If you are using the Desktop version (Windows/Mac), switch to Forms Mode (click the "Forms" icon in the top right). Open the Form 8801 Worksheet. Look for any highlighted or manually entered values in the Part 1 section. If they are there, try to trace the "source" (usually by right-clicking and selecting "Data Source").
Review Prior Year "Exclusion" Entries: The AMT credit is split into Exclusion items (which are lost forever) and Deferral items (which create the credit). If you had items like tax-exempt interest from private activity bonds or a large standard deduction in the prior year, TurboTax might be misclassifying them.
Delete and Re-import the Form: Sometimes the "carryforward" lfrom the previous year's file gets corrupted.
Go to the forms mode.

Delete Form 8801 and the AMT Credit Carryover Worksheet.
Go back into the "Federal" interview section and re-enter your 2024 AMT information manually.

If you received a K-1, check the AMT section (Box 17 for 1065 or Box 15 for 1120-S). If an "Exclusion" code was used there, TurboTax might be populating Part 1 erroneously.
