Welcome to Open Street Map! I'm just another editor, but here's a couple comments:

1. Since you added a node, not an area, that's why you weren't seeing the House tag show up. I changed it to an Address tag, which is more correct until aerial imagery gets updated and the footprint of the house can get drawn.

2. Don't dox yourself in the future by saying things like "my house", "my street", etc. in the notes. You can use source "Survey" for things you've checked in person.

I updated the office tag to "office=it", as that matches the closest.
TaxHawk is a software company that runs tax prep websites, you're correct that they don't expect public visitors.
