Sorry for the perhaps stupid question(s) and to your comment "It sounds like you may have set up your account as a business on the tax side of things" and I applied for an EIN from the IRS as a Sole Proprietor and I wanted the EIN to shield my SSN from companies I do business with.
Knowing that, I assumed I need to pay my estimated taxes under the EIN and if I do this with a business voucher, I assume that means I can't make an online payment (since 1040-ES isn't showing up as an available form) and I must send a check?
