Not sure how many are affected, but for those of us who have FTC carryovers the news about Form 1116 Schedule B is really depressing. In the past Form 1116 Part III Line 10 required an explanatory statement that TurboTax generated automatically and attached for both paper and e-filing. Beginning with tax year 2021 Line 10 requires a new IRS Schedule B. There are several threads on the topic with personal and professional preparers complaining about software (including H&R Block) not supporting the new form for e-filing, like this one: https://www.bogleheads.org/forum/viewtopic.php?f=2&t=366971&sid=8926bc3d97037651f4c8edbb90496e49&sta...
There was a ray of hope from a TurboTax employee on Feb 19 saying that they might possibly support e-filing Schedule B

But that now seems unlikely given the "E-file unsupported" entry in the forms availability table. Means I'll have to wait until March 31 to complete Form 1116, then file paper state and federal returns, again :(
