I checked the box to electronically pay the 2020 estimated tax fr my client and it has not been withdrawn from her account.   The diagnostics have an error message that says she has a balance due but the date is prior to the current date and will cause the return to be rejected.  The return was not rejected and the 2019 tax liability on her 1040 was withdrawn from her bank account

Why was the estimated tax not withdrawn?  What can I do?
