@Critter-3 Thank you so much for this reply!
I will amend the election letter as you propose to say 2019 and include it with my 2020 return and again when I send the 2019 amendment after getting the ITIN.
Now that my spouse and I have agreed to joint filings, it's no problem to include her 2019 income when amending.
Point noted on correct w-7 address as well.
Related to this, we take the Foreign Tax Credit and I suspect after the 2019 amendment my carry forward numbers calculated on the 2020 return will no longer be valid. As I always have a carry forward amount, I am hoping I can simply recalculate the table when doing my 2021 return. Are there other considerations I should take into account?
