I owe to the IRS I made payment arrangement through the turbo tax app, but IRS is sending me an invoice stating I have not made a payment. So where is the money I submitted going

How did you pay it?  Maybe you entered your bank info wrong and they couldn't pull it out of your account.  Your only proof of payment is your bank or credit card statement showing it coming out.  Turbo Tax does not pay it.  They only send your bank info to the IRS or state.

If you submitted Form 9465, Installment Agreement Request with your tax return, then the IRS will be sending you a notice in the mail approximately 30 days after the 7/15 deadline(sometimes longer).  The notice will indicate whether the Request was accepted or rejected.  Once the Request is accepted the method you requested to pay the installments will be activated.

Payment plans take weeks to approve so the payment will not happen until then ... they will send you a letter when they decide but for now you can expect the payment to happen anytime now ...  OR  you can make payments directly on the IRS web site now ...https://www.irs.gov/payments
