"to elect to file as an S-Corp"

Nothing in this topic is changed by that election.

S Corp is required to have Payroll for anyone that works for the business, including any shareholder-employee. S Corp does not have an Owner. There is no such thing as Draws or Dividends.

S Corp does not send a 1099 to its shareholder for work performed for the S Corp. It is supposed to be payroll. Those takings are payroll whether the entity is S Corp or C Corp, for the employee. But the Corporation (either formation) had the entire amount as Income in the year paid to the entity.
