Form 172 Not Supported by TT

I have a Federal Disaster Casualty Loss carryforward due to Hurricane Helene in 2024. This loss is supposed to be reported on Form 172 "Net Operating Losses". This form is not supported by TurboTax. Does anyone know if this form can somehow be attached to an electronic return? I really don't think so, since the AGI showing in TT doesn't reflect the impact of the casualty loss carryforward. I get the feeling I will be able to print several of the TT forms out from the software (i.e. Schedule 1, Schedule A, Schedule D, etc) but will need to prepare Form 1040 manually (so I can insert the loss and calculate AGI correctly, then the proper amount of tax due).

Am I missing something? Is anyone else grappling with this issue?

Form 172 cannot be attached electronically to your tax return. It will need to be printed and mailed with any applicable worksheets either with your original completed return or with an amended return used to claim the NOL.

If you know the amount of your carryforward loss, then you can enter that information into TurboTax as part of your return. The steps to take will depend on the version of the program you are using.

For TurboTax Home and Business, there is a separate Business tab at the top of the screen where you will find Schedule C, Schedule E, and other business situations. Click the Business tab and scroll to Less Common Business Situations, then click Start beside Net Operating Loss/QBI Carryforward Loss to enter your information.

For other versions, go to Wages and Income > Business Items > Business Deductions and Credits and click Start. Then select Business Loss Carryovers (NOLs, QBI) and click Start to enter your information.

For reference, here are the instructions for Form 172 and a link to the form itself:

By importing your 2024 Return into Turbotax, to start your 2025 return, TurboTax automatically includes the NOL (as a negative amount) in line 8a of Schedule 1. At no point does turbotax mention or suggest a Form 172, and so not clear why you should override turbotax with paper forms it doesn't even suggest to use. They are supposedly the team of experts who make sure that things are done properly.
