Payment arrangements

Hi, 

I owed taxes this year and towards the end clicked on can't make a payment now. Which allowed me set up a payment installment plan. I set up to have an initial payment taken out and every month a certain amount to be taken until its paid. Why can't i see my payment arrangement? No where on turbo tax does it say the arrangement was made. I set up direct deposit. Does this mean there going to pull the whole amount that I owe out? Anyone have any answers?
