Have you already filed, or does TurboTax think you were finished? If so, we can tell you how to open your return back up to go through the estimated taxes interview. Or is your return still in preparation and you can open it with "Take me to my return?"
Once you figure the amounts, also be aware that you have other payment options for quarterly estimated payments that involve no paperwork, checks, etc. The Treasury has a site called EFTPS.gov where many types of tax payments can be made, including quarterly estimated taxes or tax due from a Form 1040, etc. You have to open an account and get a PIN (which they send in postal mail). We can tell you more about EFTPS.gov.
Or if you don't want to open an account at EFTPS, you can use IRS Direct Pay at the irs.gov website, which allows you to make 1040-ES payments directly out of your bank account (free) and to print out a confirmation. There is no fee for a bank direct debit there, but there is a fee if you use credit/debit card.

We can tell you how to get to the estimated taxes interview when you answer my question above.
Thank you for your reply. We have already filed and received our 2018 refund.
See the info I left below. When you open the return back up, do not make any changes in it, since it has already been filed.
You can go through the section "W-4 and Estimated Taxes" to figure your customized 1040-ES quarterly tax payments for 2019. There is also a place in that interview to enter what you have already paid for 2019 (if applicable), and it will let you include any expected income changes or any other changes you have for 2019.
NOTE: When you open your return back up, do NOT make any changes in it, since it has already been filed.
Here's how to open your already-filed return back up to get to that section:
Here's an alternate navigation method if you have any trouble with the above.
With your return open, at the top right click on SEARCH.
Enter the term 1040-ES without quotes, and click the blue magnifying glass.
Then click "Jump to 1040-ES."
Next screen says: "Adjust how much tax you pay." It first asks if you want to change your W-4 withholdings (if applicable). Yes or no.
If "yes", it will first have screens about your W-4.
If "no", the next screen will be "Estimated Taxes for 2019" which asks if you want to prepare estimated taxes.
If you need to figure state estimated taxes, see this:
