Payment Options and "Installment Agreements"

This is not a question, it's a observation of a TT "omission".

I do a tax return for a self employed taxpayer who can't afford to pay what they owe.  As a result, they have a long-standing IRS installment agreement.  (TT has a very good explanation of the 2 ways a CREATING an installment agreement if you don't currently have one, pointing out that doing it on-line is the better way.) 

 

A problem arises if you already have one and don't want change it.  There's no "payment option" for that circumstance.  I had to lie and choose the "I will mail a check" option.  Successfully e-filed the return but the client has no intention of sending a check.  Don't know what the IRS computers will do with this situation.
