TurboTax software doesn't always ask this question. You should type in the topic search for "estimated tax payments". On the left side of your TurboTax online account you should see a black banner. Towards the middle of the banner you should see the words "Tax tools" click on that and a dropdown box should appear. Click on the word tools then you should see a place to enter "Topic search" once you enter "estimated tax payments" in the search bar click find button and it will take you to the exact place to enter those payments you made. There will be four separate places to enter the payments based on the dates they were due.
