I've already submitted 2017 taxes, do I have to recall the 2017 return?

Per the IRS website:

You may pay online or by phone. You may also pay by check or money order, or by credit or debit card. If you mail your payments to the IRS, use the payment vouchers that come with  Form 1040-ES , Estimated Tax for Individuals.
 

Check out the  electronic payment options  on IRS.gov. The  Electronic Filing Tax Payment System  is a free and easy way to make your payments electronically.
