I am using the online self employment version and as of today, it's working with additional questions asked about repaying all or part of the distribution and if some part of it is left unpaid, if you would like to pay the entire tax burden in 2020 or split it over three years.
I cannot say if any other version is working but I heard elsewhere that the download version gets updated overnight so if that's what you're using, I would try again tomorrow.
