I am not sure how exactly my balance due is being paid. I think i signed up via turbotax to pay the IRS from my bank account, nor do I understand the payment vouchers.

I have multiple payment vouchers attached to my tax return document. One of them is for the lump sum (For 15th of April), and lets me know that I elected to pay from my bank account. But then there are 4 others, spaced out from now till January for smaller amounts that add up to the lump sum. I dont know what option i chose to pay my taxes. Also, when i check my IRS account on their website, it still says my Federal tax has not been processed yet even though they accepted it on FEB 1st 2018. Turbo Tax's call center system wont work for me, no one is ever on the other side of the phone, and the IRS doesn't have any options over the phone. Does anyone have any advice or answers?
