Adalmaneric, to be clear, Form 1116 IS supported by TurboTax, both electronically and via mail. It's the new Form 1116 Schedule B (which is needed for carryforwards/carrybacks) that will only be available via mail on 3/31/22 and is not supported electronically. Unfortunately, most people who need 1116 also need 1116 Schedule B so this is kind of a moot point.
