How do I find the date of my scheduled IRS tax payment? I also need to know the bank account number used for the scheduled payment.

To confirm the scheduled direct debit payment, you would need to access a copy of your tax return. The scheduled debit date for a federal tax payment would be listed on the Federal Information Worksheet-Part V. The debit date for a state tax payment would be on your State Information Worksheet-Part V. 

Please take the steps below to obtain a copy of your complete  tax return with worksheets.  

• Sign in to your account (if you haven't already done so), using the same login you used to file your return.
• Scroll down to My Tax Returns and Documents and click show.
• Next scroll down and select Add a State (you are not really adding a state, this will allow you to get back into the program.
• In the left side panel select Tax Tools then select Print Center.
