I've encountered exactly the same problem. TurboTax needs to fix TWO problems here:
(1) The BUG that insists there is an estimated value where in fact there isn't (and won't allow continuing with the return). Even if tech support includes it in a canned response, forcing users to delete and recreate forms is NOT an acceptable solution.
(2) The incomprehensible error message telling an end user to change a value identified only by a cryptic internal code name known only to the developers.
As a different person said in another post, I've used TurboTax for years, but it keeps getting worse, not better. Other options are available and I've started advising others to avoid TurboTax. If you can't get it together, you'll lose many more customers.
