Hi @DanMur
Additionally , Make sure the identification info (last/first name, DOB, SIN, address, direct deposit, etc) entered matches what Revenu Québec has on file otherwise you can't Netfile and you will need to contact Revenu Québec to update them.
Also you can't Netfile if one of these restrictions apply: https://www.revenuquebec.ca/en/citizens/income-tax-return/filing-your-income-tax-return/filing-your-...
