Get your taxes done using TurboTax

"You should be able to efile your return and send the 3520 by mail." 

Yes, exactly - but 2023 and 2024 Turbo Tax will refuse to allow E-Filing if you state in your 1040 that you have 3520 and 3520a forms to file. You should be able to E-File your 1040 and send form 3520 and 3520a by mail, but TurboTax no longer allows it.

This is a bug in TurboTax 2024 and 2023 - how can it be reported? I have not found any way to inform Intuit so they can fix the issue.
