EFTPS doesn't list 1040-ES to make my estimated tax payment

I am a first year sole proprietorship and I am wanting to make my estimated tax payment. I have an account on EFTPS under my Business EIN/TIN however when I click payment, there is no 1040-ES form listed nor any form that has estimated so I am confused as to how to make the payment. I'm hoping someone can clarify how I go about this....I also have an account on Pay1040.com and if I select Make a Payment and select Business, there is also no 1040-ES form listed.
