It could be that TurboTax has determined that you don't need them based on your 2018 taxes. If you expect to owe more than $1,000 in 2019, you may incur underpayment penalties if you do not make your estimated tax payments. Go back into your return and go to the section on estimated payments. Work through the questions and at the end it will show your estimates. You will need to print those out.
