2/12 is not over yet. Updates are usually done late at night. I have asked TurboTax many times (in past years) to post the release date the day *after* because many user see the date and expect it to be there first thing in the morning what it will actually be there first thing the *next* day.
However, updates do not just affect a single form or fix, updates have many fixes and a problem found it any fix can clause the update to be held. Not only do the several online versions need to be updated, all Mac and Windows users get the same update for the 8 different desktop versions and it takes a long time to download and apply desktop updates so TurboTax tries to have as many fixes in an update as possible and as few updates as possible so that desktop users will not be updating every other day. That is one reason why updates and forms can get delayed.
This is not unusual at all and has occurred many times in years past.
