Typically you can find where it would be as a default by pressing F1 at that entry point. In this case it does not say anything, so my initial guess is NO. 

If  you go to Settings > Client Letter > you will not find any "options". You can take the text of the Direct Pay Section and copy it, then paste it in the Main Letter Body in each of the 3 IRS Address (Payments...) sections as a more generic version such as "As an alternative to paying by paper check, federal income tax payments can be made using the IRS Direct Pay electronic payment method. This service is free and can be used to pay your individual tax bill or estimated tax payment directly from your checking or savings account. To access online, visit www.irs.gov/payments for more information. This may be done in lieu of using 1040V and/or 1040ES"
