Paul,
The simple way, if you are struggling w/ this, is to pay someone to set it up for you. I do mean that in all seriousness. If you have spent 20 non-productive hours on this, that you could have used on something productive for your business, then you need to consider what your time is worth. I'm guessing it is worth more than that. Given that you put so much effort into getting it going, I'm also guessing that you believe that using QB w/ QBI will be worthwhile for your business. So bite the bullet and just pay someone to get it going for you. The sooner you do it, the more worthwhile the $$ spent will be in time savings for you.

My thoughts
