This answer recommended answer is from 2 years ago. Shouldn't this have been fixed by now? I had the same problem. 1099 step by step lets me select 4 countries, but after inputting one country amount it doesn't let me input the others. Overriding the imported amount and creating dummy 1099s seems a kludge and likely to interfere with e-file (e.g. overriding calculated fields prevents efile), so I didn't try this and had to give up the foreign tax credit.
