You can verify if you have scheduled step-by-step payments and the dates by accessing a copy of your tax return. The scheduled payment would be located on your Federal Information Worksheet Part V Information worksheet which is included with your tax return.
How do I get a copy of a return I filed this year in TurboTax Online?
If you chose to have them withdrawn from your bank account, generally, the funds are withdrawn on the payment date you specified if your return has been accepted. If you still don't see the debit 7-10 days after your return has been accepted and your specified date, you will need to call the IRS e-file Payment Services at 1-888-353-4537, if this is a federal tax payment you owe. If you didn't specify a date, then April 15th is the default payment date.
If you did not set up your Federal payment with TurboTax you can go to the IRS website to pay.
