Can I pay my federal tax now, instead of waiting for the electronic transfer scheduled on April 18?
You will have to contact the IRS e-file
Payment Services 24/7 at 1-888-353-4537 to cancel your scheduled payment, but please wait 7 to 10 days after your return was accepted before
calling. After you cancel the scheduled payment, you can pay your taxes owed by visiting
the following IRS link: https://www.irs.gov/Payments
