@paradisepro if you're comfortable with forms mode and what you need to enter, then the sections that are currently not available are probably available at forms level tho I've not tried entering Schedule D or 1099-R that way.
If you are trying to estimate tax on an IRA conversion to Roth (is that you mean by "rollover"), you would also need the tax calculation on Form 8606 if you have any basis in the IRA. You can also calculate by hand how much of the conversion would be taxable and possibly just put that in as a 1099-INT to get it into ordinary income.
It may be simpler to work with a different online tool for estimation, folks have recommended this
