This TurboTax support FAQ is probably the closest as you will be able to get to product management addressing this issue - https://ttlc.intuit.com/turbotax-support/en-us/help-article/tax-return/e-file-1040x-amend-return/L9t...
Generally, you can e-file your amended 2025, 2024, or 2023 federal return via TurboTax if your original return was also e-filed in TurboTax.
However, there's a chance your return can't be e-filed based on your unique situation. If this happens, you'll need to print and mail your tax return.
