I filed my taxes electronically in February 2019. The Turbotax file indicated on page 1 of 2 that there were only two vouchers to be paid (#2 and #4). Page 2 of 2 provided instructions for filling out the checks or money orders for payment, and the next two pages were the actual ES-540 2018 Forms (#2 and #4). Didn't run out of paper and it didn't print on the reverse side. The saved PDF shows the same exact thing. Since I did not prepay any taxes for the future 2019 filing, I can only assume that there was something wrong with the Turbotax program. I should have known better however, because I have been using Turbotax for years and have only being paying California 3 times a year. My bad I guess, but it is irritating to get hit with an unexpected large payment and a penalty.
