I need help with revenu quebec filing (gst)

I am trying to file my expenses as I was self-employed last year. I filed my federal income tax without anymore problem but for provincal, it keeps asking me to enter a GST number but i dont have it and i did everything i could to avoid that question. Its not letting me file without skipping that question. I have also called my employer and Revenu Quebec and they both told me I didnt need to enter a GST identification number. Please help.
