I am preparing my 2021 tax return and I have foreign income earned through a mutual fund. The 1099-DIV shows that I paid foreign tax. While filling out form 1116 Turbo Tax indicates that I need to amend my 2019 return due to a carryback. IRS publication 514 discusses a carryback to the previous year but not 2 years back. Can someone explain how to reconcile the 1 year carryback in publication 514 with the 2 year carryback in TT?
