Expat with a SMLLC, didn't get an EIN, never filed 8832. Am I doing something wrong?

I formed a new company (which is basically a single member LLC) in Sweden in January 2021. As the title says, I didn't get an EIN, and never filed form 8832 to choose this as a disregarded entity. I contacted a CPA who told me that it was too late to make the election to treat this as a disregarded entity and that the IRS would treat it as a corporation, hence they recommended that I file form 5471, which I did in October as part of my 2021 taxes.

 

Now, that I had the time to read up a little on this topic, I'm not really sure if this was the right thing to do. What I understand is that, as a SMLLC, the IRS would automatically treat my company as a disregarded entity, so there was no need to file other forms (not even 8832). I would of course prefer to treat my company as a disregarded entity so everything is reported in Schedule C which is much simpler.

 

Can someone please help me and tell me if I am mistaken and what forms are the ones that I need to file? Now that the 5471 is filed, should I send an amendment?  should I continue filing 5471 every year? or should I send a 8832 to make the choice to treat this as a disregarded entity?
