You are not required to keep the worksheet in your program.
You would need to keep the worksheet in your program if you want to have the carryover credit applied automatically to next year's return in TurboTax. Otherwise, you don't need to file it with this year's return since you can't claim the credit this year.
You may be able to delete the form 1116 to remove it from your program.
A simple way to delete forms in TurboTax online is to use the Tax Tools menu option, which is on your left menu bar when you are working in your program. Then, choose Tools and then Delete a form.
If you are working in the download TurboTax program, use the Forms Mode on your menu bar to bring up the form you want to delete, then choose the Delete Form option at the bottom of the form.
