I had my tax return rejected because of an error on form 1116. It said amounts had to have a country assigned. I only had one country where I had foreign income but somehow a second country got checked. The IRS rejected even though all amounts were blank in that column. The only way that I could find to fix this was to go into the forms view and uncheck the box for column B (stumbled on this). This seems like something that TurboTax should pick up upon but there were no error messages provided.
