This happened to me just now - The same basic error message, except for Form 8801, Credit for Prior Year Minimum Tax. It apparently won't be available until 3/17/22.
Customer support was maddening. They kept using the nonsensical excuse of "The form hasn't been provided to TurboTax." WTF is that supposed to mean? Form 8801 for year 2021 is posted on the IRS website RIGHT NOW!

It's been "provided" to everyone on the planet!
I should have found this e-mail thread first - it would have saved me 30 minutes of frustration and dealing with incompetent support.
The error is very poorly worded, almost coming across as blaming the user. It should really say "We're sorry, but we don't have our act together - please try again later after we've sobered up."
