IF you could be paying the estimates thru the TT SE program then you should see the payment being withdrawn from your real bank account or show up on the credit card statement ... if this did not happen then you did not pay them. And IF the SE program is doing this then you are being linked to the IRS site and you just do not know it ... don't forget about state estimates if needed.
Also the EIN is important to use ... when anyone asks you to fill in a W-9 for 1099 reporting you really should use the EIN so you are not spreading your personal SS# out where it can be picked up for fraudulent purposes. This is a Identity protection that you really should be using. On your tax return, in the Sch C section you will enter the EIN and then the Sch C will report both your SS# & EIN so all tax reporting forms in either number get married to the same tax return.
