Unable to use NETFILE

[obi-o]

I am trying to file my taxes for 2021, and it's not letting me file through NETFILE. I had already file one for 2021, and had two more from 2021 to file, but i'm getting the error below

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

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.

Please what can I do to resolve the issue?
