It sounds like my situation is a bit different. I DO have a business credit I'm trying to claim, and so I do need the form. I'm a sole proprietor with no employees, so as I'm guided through the business credit section in Turbotax the software tells me I DON'T need a business registration number. However, when I look at my errors in review, I see one on the Investment Credit form (again, that I need) telling me I need to enter a registration number in 2A.
So, going back to my original question...do I actually need a registration number (contrary to what the software says), or can I instead e-file my return through Turbotax despite the error?
