I filed my state and federal tax return using Turbo Tax Deluxe. For my federal tax return I signed up for the installment payment plan by following the steps on TurboTax at the time of filing. I entered an initial payment to make along with the monthly payments after. After transmitting the return it said there are some documents that need to be sent. The document had a voucher with the amount that I specified in the initial payment for the payment plan. It says mail a check or money order. Do I need to make that first payment I specified in the payment plan through a check or will it be automatically deducted from my bank account? Basically do I need to do anything else or not? My federal return has also been accepted but I haven't received any notification on whether my installment payment plan was accepted.
