Same here. The review ran with no errors a couple of days ago. Tonight TT updated my software (I did not make any changes to my return) and now I have this error and can't uncheck the box or delete the form.
I have the same problem... Look forward to an answer... Seen some related answers to delete the 2210 form, but I will wait until maybe someone else answers this question... Might have to do with the update, that I also applied... Or for me, I modified some information on passive losses - and that dropped the amount of taxes I owed, and maybe this triggered the problem... I dunno... but thanks for asking the same problem I have... frustrating as it shows you the box to uncheck in the review, but it doesn't let you uncheck it... Like TurboTax is playing with your patience...

OK... that worked... says that Intuit is working on a fix to the problem, and you can sign up to get notified when the fix is ready... that is good news, indeed...
TTX is working on it....and There is a "Sign Up" in this FAQ
