I am having the same problem, rejected twice. I am using TurboTax 2020 Desktop and have tried to manually enter the data in Form 1116 but it still wont process.
This is the first year I am using TurboTax, I had an accountant file for me in prior years. I do have foreign tax credit carryover, however none for 2020.
I welcome any advice on how to properly file this.
