Extension Rejected, But TurboTax Payment-Due Amount Not Updating (Still $0)

I filed an extension and it was rejected for the reason below. I believe the pending tax payment (via bank withdrawal) should be canceled.

Issue: However when I open TurboTax the federal taxes due is still $0. This is the case both if I go to my pending federal return AND if I attempt to re-request an extension. How do I fix this?

Rejection reason: Taxpayer TIN in the Return Header must not be the same as a TIN of a previously accepted electronic return for the return type and tax period indicated in the tax return.
