I am completing my tax extension, but it is asking for banking info to pay my federal taxes again, even though I paid them back in April. What am I doing wrong?

You are not completing your extension. The extension is what you filed in April. What you are doing now is completing your tax return.

In your tax return you have to enter the payment that you made with the extension in April. To enter the payment you made with your extension, type "estimated tax payments" (without the quotes) in the Search box, then click the link that says "Jump to estimated tax payments." That takes you to the screen that says "Estimates and Other Income Taxes Paid." Scroll down a little to the second section, "Payments with Extension." Click the Start, Update, or Revisit button for "Payment with 2023 federal extension."
