Canadian Citizen W-8BEN

Hi there. Brand new to the forum and really need assistance. I am a Canadian resident that has inherited Mineral Rights in the US, primarily Oklahoma. I’m in a situation where I’ll be receiving a decent check and require filling out a W-8BEN form. I’m unsure if in Part ll line 10 if there is a special rate with a Canadian and US tax triety. I sat on hold with the IRS for a long time just to be transferred to a line that no longer exists and disconnected me. Hoping there might be other Canadians on here that could help. Thanks

I’m in the similar situation. I go to a US tax specialist. They do my state, federal, and Canadian taxes. To confusing.
