I already filed tax before knowing extension to July 15

Hello 

I already filed and i got confirmed both are accepted by Federal and California. In fact, I owed $15,000 to federal. I set up payment date is Apr 13th.

Since IRS extended to July 15th, can I withdraw my submission and re-submit later?

You are unable to change your payment date in TurboTax once you filed your return and it has been accepted but you can cancel it and then make other payment arrangements with the IRS. 
Federal Tax direct debit payments can be canceled up to 48 hours (midnight, Eastern time) before the date you designated the funds to be debited. To cancel your direct debit transaction, call (888) 353-4537.But please wait 7-10 days after your return was accepted before calling.

State : For your State direct debit payment you would need to contact your State directly to see if you can change the date or cancel the transaction. Each state is different you can find the contact information for your State by using this link to find the contact information for your State:

Thanks for your answer. It is great.

One more. After cancellation of payment, how can I pay my owed tax?

Thanks in advance.

When you cancel the payment, you can then make another arrangement with the IRS for your taxes owed. 

This can be done using the same telephone number as above.

Can I arrange payment thru IRS web-site?
