It isn't clear who guided you to only pay yourself quarterly, because you told us you are taking company funds monthly for that benefit to you, personally, as the employee. The employee-shareholder requirement is for Payroll as Reasonable Rate for services performed, and using the company money but delaying reporting this as a Payroll event, as taxable, is pretty much violating that requirement. While there is a strategy for After the Fact payroll, it isn't used with something so obvious and, to use a phrase I use in class = Discoverable. You have a Monthly activity that relates to Payroll, so you should be running this through Monthly payroll, at a minimum frequency. Not Quarterly.
