I believe you misunderstood, -your estimated payment and voucher for 2016 is not related to the 568 for 2015 from what I understand.
I also opened my LLC in July 2015, so I owed $800 as of October 15. I paid it via a 3522 voucher online this month with late fees and listed it on my 568 for 2015. If I were to keep my LLC open, I would also need to go on line by 4/15/16 and pay an estimated 2016 payment of $800. This amount would then be referenced when you complete the 568 for 2016. The voucher number is different I believe. Hope this helps. Please check with the SOS since this is so confusing.
