How can I change my election for payment method on my federal balance due? When I filed I chose ACH, but I now want to mail my payments.

You can cancel the payment after your tax return has been accepted by the IRS.

See this IRS website - https://www.irs.gov/payments/pay-taxes-by-electronic-funds-withdrawal

• Once your return is accepted, information pertaining to your payment, such as account information, payment date, or amount, cannot be changed. If changes are needed, the only option is to cancel the payment and choose another payment method.
• Call IRS e-file Payment Services 24/7 at 1-888-353-4537 to inquire about or cancel your payment, but please wait 7 to 10 days after your return was accepted before calling.
• Cancellation requests must be received no later than 11:59 p.m. ET two business days prior to the scheduled payment date.
