CRA Result Code: NETFILE submission already confirmed

[afzama]

I receive the below result code when filing.
Any recommendations on how to resolve?

Note:

1. I already reattempted two other additional Netfile codes after a few minutes -  found from my previous NOA.
   Received the same submission message, 4 times.
2. I suspect I am receiving this error due to submitting my self-employment return prior to my personal tax return, using netfile code from last year's NOA.  

Next Step to file your return
We're sorry, the Canada Revenue Agency was unable to accept your NETFILE tax return.

Message from the CRA:
CRA Result Code:
NETFILE submission was already confirmed. Not letting this second submission pass through.
Do a REFILE.

You have 2 options:

• Recommended - Try NETFILE again in a few minutes.
  Please note: You only have 5 attempts to NETFILE your return before the CRA will lock you out.
  If the problem persists, please contact TurboTax Customer Support for assistance.
• Print and mail your return to the CRA.

The first time I submitted my tax return, I received this notice. I'm starting to become frustrated because it says I cannot resubmit a second time when I haven't submitted the first time. According to the CRA, they have not received any documents from Turbotax and its costing me money.
