S corp Form 941

Single member llc with s corp election and only one employee (myself)

Do I pay payroll taxes and tax withholding for form 941 with the s-corp business bank account or my personal account? (I would think these are paid by the LLC bank) And would these be paid using EFTPS with my ein or the eftps with my SSN?

What about estimated tax payments 1040es? (I would think these are paid by my personal bank) And would these be paid using EFTPS with my ein or the eftps with my SSN?

When planning personal estimated tax due, I see I can safe harbor by paying at least 110% of taxes due last year. Does either of the fica portions (employer fica 7.65% and employee fica 7.65%) of taxes paid on my waged salary count towards this threshhold, or just the income tax withholding?
