I had to override the field line 13z on Schedule 3 in the Form 1040 Worksheet in order to enter a tax payment by my client that was made after the due date for the income tax return.  I request that Intuit consider allowing tax preparers to enter tax payments on line 13z of Schedule 3 without having to overide this field (which requires turning off error checking before e-filing).

The IRS instructions for Schedule 3, line 13z are general and do not limit what can be entered on this line.
