Sale Of The Application In The Microsoft Store

Hello. I create small games / useful applications and upload them to the Microsoft Store. At the moment, whatever I have in this Store is free. Now I'm changing the settings of one of the applications and I want the sale to be, say, the sale to take place only in the USA. So far so good, but in order to make the settings so that I can be paid, Microsoft asks me a bunch of questions, gives me forms to fill out, and the like. Example question: "Is the income you receive from Microsoft effectively connected with the conduct of a trade or business in the United States Persons / entities must file an annual US income tax return to report income claimed to be effectively connected with a US trade or business (See Effectively Connected Income) "They ask me if this income will be my Effectively Connected Income (ECI), and they say that in most cases if I'm not from the USA they are not, but there are exceptions. And if I doubt to consult TAX PROFESSIONAL. I'm not sure what ECI is. I shook the internet ECI as well as tax advisors. I will probably have to inform the NRA about my income from the Microsoft Store for each year. Someone who has been through something like this, please explain to me how things are, should I go to a tax consultant. Will this consultant be competent precisely for such revenues from internet sales in the USA including digital products such as "Store" applications? I think the most useful will be someone who has already gone through something like this from my point of view. Living in Bulgaria, selling in the USA. Or someone who understands from taxes and selling computer applications. I do not know where to look for such people. My first thought was to share here. but there are exceptions.
