@luisemalloy550 since Portugal; uses a calendar year as tax year , I am confused as to what you mean by :
"claim a credit for tax paid in 2023, then I guess I put my 2023 income on Form 1116, though that tax was on 2022 income."
Your US tax is on 2023 income and Portugal tax is also on 2023 income. Perhaps you have not completed the 2023 Portugal return. Note that as a US person whom is abroad on the April 15th ( US Tax Day ), yous filing date is June 15th. Although the Tax pay day still remains the 15th of April.
Hope this helps -- you can settle the Portugal return before you file the US return
Is there more I can do for you ?
