H&R Block and FreeTaxUSA.com have form 8396 with no issues and you can file now.
I received the same message that From 8396 would not be available until February 10, 2022, and today I signed and it now says February 17, 2022.
I love Turbo Tax and have used it for 20+ years. But, today I went on and did my taxes on FreeTAXUSA and filed it already with form 8396. It is free to file Federal Returns at FreeTaxUSA.com so I saved $29.99 as well! I would have never tried another Tax Service but not having the form 8396 I decided to try it and did. It worked great!
