Deductions & credits

I am not able to take any of the foreign tax credit due to no taxes paid or owed in 2025 and I would like to carry forward 100% of the under $600 amount to future years.    

I tried your suggested steps below and the Form 1116 and worksheets do appear when I adjust the foreign tax credit to over $600 but when I adjust back down to the actual amount of $500, the form 1116 and the worksheet both disappear.    I was not able to replicate what you did because maybe I did not use any of the credit in 2025?

Based upon your reference to IRS Topic 856, I need Form 1116 in order to allow carry forward.

Is my only option now to convert from Turbotax Online to Turbotax Desktop and create Form 1116 in forms mode as I have seen recommended in other community chats?   

It seems like Turbotax Online is flawed in this particular situation since it won't allow me to produce a form 1116.   I guess I could force my foreign taxes to be above $600 to produce Form 1116 and allow carryforward and then adjust the carryforward down when I complete my 2026 tax return?   This will have no impact on my 2025 tax return since I am not using any of the foreign tax credit in 2025 since my taxes are -0-.

I appreciate your help.
