I called TurboTax customer service to ask if you can currently e-file an amended 2023 tax return if using the Online version. After looking into it, their answer was No. Doesn’t matter if it’s the Desktop or Online version, neither allows for an e-file of an amended 2023 tax return as it is past the October 15, 2024 closing date. You would have to print off and file a paper return.
