Form 2553 questions

[Matt Good]

Under item E for effective date of S election I'm instructed to begin my first tax year, with no prior tax year on January 7.

Under column N I'm asked to enter the month and year that each shareholder's tax year ends... What do I enter?

I JUST applied for my LLC and I'm the only shareholder at 100% with no earnings to report, yet. My CPA advised me to just complete all docs myself given my situation was simple. This is the only part that I'm hung up on.

Help!
