It is possible that the verbiage for the mobile editions is incorrect. Since the TurboTax online editions are now only for tax year 2024 it would make sense that only the desktop editions for 2023 can be used to amend a 2023 tax return..
You will have to contact TurboTax support for assistance with this problem.
