Business number (BN) problem - Quebec 10-digits

7 0 1

Hi! I'm setting up my shop's payments and taxes. It asks for a 9-digit Business Number, but businesses registered in Quebec have a 10-digit number (NEQ). Do we leave out one of the numbers? Or is there some other way to make it work? I chose sole proprietor even though we are a partnership because it didn't require a BN, I'm not sure if that will be a problem down the road.

The sales tax section is not letting me input our tax numbers, and I imagine it's because we haven't added our business number. 

I was able to add my GST and PST numbers.
However, there is no longer a section to choose our business type (i.e. sole proprietor, partnership, etc.) or add the Business Number. Any advice?
