Update - support advised as a work around to ensure there are no other errors int the return, then use the main menu bar to:

1. E-File

2. Electronic Filing

3. Convert/Transmit Returns/Extensions/Payments

4. Uncheck (it wont persist after this cycle) "Enable conversion error checking" under "Convert/Transmit Returns/Extensions/Payments"

5. "OK" and submit the return.

This process worked for me, your mileage may vary......

I can see a need for a "flag" to notify us of the expired date, but also an option to allow us to ignore it once notified.
