How do I pre-pay my Estimated Taxes for 2020? The instructions don't work. It says click on button & choose from the list of forms. No such options exist.

I have read all the help files, but none of these options they tell me to do exist.  I've already filed 2019 and I unexpectedly have some income now that did not have taxes taken out.  1040 ES does not appear in Tax Tools, Print Center or even when I follow the one that says Amend and Add A State but don't actually add a state.  This should be much easier.
