Get your taxes done using TurboTax

I've recently hired a nanny and have enrolled in EFTPS using an EIN I obtained from the IRS. When I try to remit my taxes, it doesn't offer a 1040ES as an option. I have tried to enroll 4 times as an individual with my SSN, but every time I get a "mismatch" letter from EFTPS saying what I've entered doesn't match the IRS. I want to remit the taxes as you've suggested using a 1040ES (because I have no other business or employees), but it seems it's not possible to enroll as both an individual AND with the EIN. What am I doing wrong? Any other suggestions? Should I have enrolled in EFTPS as an individual before obtaining an EIN?
