@Clamptown The reason why TurboTax shows warnings is to get your attention to some information in your return because the software is not sure, and, depending on your personal situation, it has no other way of finding out than asking you to have a look at it. This is why you must indicate if this applies to you or ignore.
If you are receiving a NETFILE error code, we invite you to verify if it's part of the error codes CRA is still working on:

Thank you for choosing TurboTax.
