I filed my extension with an estimated payment and bank routing numbers...how can I confirm my payment was made?

Has your extension been accepted? 

Generally, funds are withdrawn on the payment date you specify if your extension has been accepted. You'll want to check the bank account you used to make your estimated payment. If you still don't see the debit 7-10 days after your extension has been accepted, you will need to call IRS e-file Payment Services at 1-888-353-4537.
