IRA Distributions step-by-step

Is there an estimate of when the IRA Distributions step-by-step will be available? I checked the Forms Availability tool for 1099-R, but it doesn't appear that 1099s are tracked there (maybe because they are not filed).

It is the time of year for playing what-if games with Roth conversion amounts, so it would be nice to have (yes, there are other calculators that could be used).
