I have seen that interview many times! Also you have the option to pay based on 100% of 2017 taxes, or a percentage based on your expected 2018 taxes. You exact options may depend on your income. In some cases, that option may not appear on the screen. However if you go to the estimated tax worksheet in Forms view, you will see the different options and the amounts that would be due as estimate tax under each option. When in Forms view, be careful not to select the option that is only available for farmers and fishers - it can be easily checked by accident, and of course it's one of the lowest payment levels if not the lowest.
