For the first time TT printed estimated tax forms for 2018. Used TT for years and never had these - why do I have them now and am I required to pay these in advance?

TurboTax usually includes 4 quarterly 1040-ES vouchers with your printout if you didn't withhold or pay enough tax this year. The program does this to avoid a possible underpayment penalty on next year's taxes. However, you're not required to make estimated tax payments; it's a suggestion based on the info in your return. Please review the following link(s) and the link(s) embedded on the webpage(s) for more information:
