I also filed electronically and scheduled a payment for April 15. However, you can subsequently cancel the payment and mail a check on or by July 15 - the new deadline - if you desire to take advantage of the extension. Though the IRS call centers are not staffed during the quarantine period, you can do this by using the IRS e-file Payment Services automated feature. Call [phone number removed], and the system will prompt you to enter your SSN, payment amount, and bank account number to verify your identity. You will then be provided the option to cancel the ACH.
