I owe taxes and would like to wait to submit until April 15th. In the past, I could choose the date my taxes were efiled. Is this still possible? If so, how?

In the File section of the program on Step 2, when taxes are owed you can select to pay the taxes owed by mailing a check and mail the check before the due date.  Or you can select to pay the taxes owed by direct debit from your bank account and select the date you want to pay on or before April 15,2025.

You can also use the IRS payment website to pay the taxes owed - https://www.irs.gov/payments
