I think the issue is that you really do have to include your foreign source revenues in the proper place on both forms 2042 and 2047. I can only go by how ClickImpots handles this sort of thing, but basically when using ClickImpots, you fill out an information form as part of the 2047 form. That puts the numbers on the proper line or space on the 2047 form and then carries the totals over to the boxes on the 2042 form.
Ah, but the French fiscal approach strikes again. Per last year's forms, I see that line 221 (on the 2047 form) reads "Total des dividendes et jetons imposables" and is supposed to be the total of lines 208+210+220. You then are supposed to split the amount on line 221 up into the categories on lines 222, 223 and 224. And it's line 223 that they tell you to carry over to 2TS (on the 2042 form).
OK, I admit I only figured this stuff out because my DH has various investments here in France - and when you get your "filled in" tax forms (online or in paper version), you get them with certain lines (like 2TS) itemized for the various sources of the figures that are accumulated for that line. (In our case, a listing of the banks and/or other financial institutions that have reported the various types of income to the Fisc.)
Yup, it's complicated - but OTOH, back in the old US of A the IRS just lets you sweat not knowing what information they have received about your income. At least here, they list it out for you so you can check it against the documents your banks and financial institutions have sent you - so you might actually know if something got "lost in the mail." And yes, it is a little unnerving how many times you have to include certain bits of information on various lines and spaces on the same tax declaration.
However, if you have set up your Espace particulier set up you can access it and then click on the menu bar where it says "Documents" where you should be able to see what you filed for the last few years. You can go to the "documents liés" to find things like the "annexe" forms (2047, for example) and the declaration of your foreign accounts. Ours goes back to 2020 (i.e. the 2019 calendar year). Taking a look at what the Fisc has on file can be very useful. (Though I do note that last year's pensions from the US show up for some strange reason as "Alaska" for the source country - though prior years are just fine with "Etats-Unis").
Not sure this answers your specific question, but it does give you some additional resources to try to figure out what's going on.
