The payment plan would be for current (or past) taxes due.
The 1040-ES payment vouchers would be for your 2017 estimated tax payments. If you’re at risk for an underpayment penalty next year, based on your
2016 information, Turbo Tax will automatically calculate estimated tax payments
and prepare 1040-ES vouchers for you.The dates on those vouchers are not arbitrary, they are due each quarter and the due dates are printed on the vouchers. There should be four vouchers...one for each quarter.
Estimated
taxes are highly recommended but not required.
