How can I validate if I entered my banking information for payment to the IRS after my return has been filed and accepted?

Much too early to look for payment. It will be at least 3 weeks before that happens 

The bank information you entered will be on the Filing Instructions page for the federal tax return.

 

To access your current or prior year online tax returns sign onto the TurboTax website with the User ID you used to create the account - https://myturbotax.intuit.com/

 

When you sign onto your online account and land on the Tax Home web page, scroll down and click on Add a state. 

This will take you back to the 2022 online tax return.
