Deferred Payment

I filed my taxes as self employed, I received an amount I have to pay by Dec 2021 and the other by Dec 2022. I have my own business, and  EIN number. When doing my taxes I was asked how I got paid I put cash, and it asked for my company name and I typed that in as well as my EIN number, but what was filed was an individual 1040 ES. When I look at my tax documents on the page where it says Total Business Profit and Losses my EIN number and company name are there. I filed my taxes jointly with my wife, how do I know where I need to pay the deferred payment and under who? Would it be under my name? Or The company name? And how do I know who's primary on the account my wife or myself? 

If I need to register an account with EFTPS who should I register it under? Myself or the company name? I also have to pay taxes I owe,  where do I make those payments?  On the IRS website or somewhere else?

Is this where the deferred payments are made? 

Help please
