Thank you all for your replies, which I really appreciate. I'm afraid that the more into the weeds it gets, the more I’m becoming confused (admittedly, I'm not great at this stuff) so I have more questions…..
So far it looks like none of the forms mentioned in your replies (1120-F, 941 or 8832) have been filed.
Although as I understood, I took the check the box election in 2018, and this is what my accountant has said in an exchange we had last year:
"In 2018, the 962 election was taken; this resulted in 0 tax being paid on the GILTI income.
In 2019, there was GILTI income of $16973; however, you still paid 0 tax; the FEIE against your earned income, foreign tax credit and standard deduction reduced your tax liability to zero."

Perhaps it would be easiest to show the forms that were shown on my returns for my last two years, 2018 and 2019, which you can see here:

Also, could I just avoid this source income situation all together by saying I’m on holiday (not working) while in the US for these 3 months?
Sorry again for all the questions! I hope this clarifies my situation a bit more.
