Form 2106 relates to employee-related business expenses. For most taxpayers, this deduction has been suspended by the new tax law changes until 2025, I believe. You'll probably just need to delete Form 2106 altogether in order to complete your e-filing. See the TurboTax FAQ below for instructions on how to delete a form in TurboTax Online.
