Thanks for your help!  USER error.  I read the business address number as business number - when I replaced that with the street number everything seems to now be ok.  insert embarrassed smiley here!

We all do it.

With Turbo tax 2022 I have the same problem.

After trying all possible combination I called trubro tax help line. 

I spent almost 3 hours with a very pleasant employe, on the end of conversation she told me to start it all-over my return. I did and the same thing happened. I decided that I will mail it in to CRA and Revenu Quebec.

I had the same issue as you when trying to file my taxes with turbo tax 2022. No matter what I entered in business address it said I am missing information or using an unacceptable character (Even though I tried every variation combination and entered no unacceptable characters).  To fix this issue I had to go to the T2125 form for my business and enter a MATCHING address in the address field on that form. After that, I went back to fix the issue and the error message stopped appearing.
