I am having a problem with my tax and need help to understand the purpose of a field. When I put in an amount or % in the field pointed out in the screenshot, the tax seems to work. When I leave it at zero, it doesnt work. The downside is that when I have an amount in that field it is requirding additional money. How do I keep this at zero, but get the tax to work? What is the purpose of that field?
Thanks so much for your help.
I hope to eventually have this all figured out and working soon. It is taking me waaaaaayyyy too long.
