You do not have to list each country, particularly if the dividends are from a mutual fund. Use "RIC" that you will find in the country drop-down menu [Scroll UP to find "RIC", not down]. In the 1099's make sure that RIC is selected for both imported name and the TT name (the boxes are next to each other on line 8). You can then report all the foreign dividends as a total, which is what the 1099 from your broker will normally show.
Then check the Form 1116 to make sure no "various" survives and the date in Part II box L date is not left blank and is in a format like 12/31/2020 (other dates work too).
Even if you have multiple 1099's with foreign income, you need only one Form 1116 if it is all passive income. If all passive income (box c: Passive category income), report it to the same Form 1116 in Box A. You only use the other boxes if you are checking one of the less common foreign income source boxes a, b or d-g. Very few will have other than passive income, but of course seemingly anything is possible.
The rejection is probably not related to the Simplified AMT unless you entered something on that form yourself or you have some unusual circumstances elsewhere in your return. Do check in Forms Mode for error flags to see if something else is amiss with any of the forms listed under Forms in My Return. Simplified is what most of us use, and to change methods requires, I believe, IRS consent -- short way of saying do that at risk of protracted pain.
Hope this helps. Let us know on the board if you find what was causing your rejection so we can share additional solutions.
