Currently I am working with the Turbotax Premier. How can I input foreign tax credit?

Here are the steps: 

• Open up your TurboTax account and select Pick up where you left off
• At the right upper corner, in the search box, type in "foreign tax credit" and Enter
• Select Jump to foreign tax credit
• Follow prompts

If you have paid taxes to both foreign and the US tax authorities, the IRS allows you to claim a foreign tax credit on your US tax return.  To claim this foreign tax credit, you would need to file a Form 1116 Foreign Tax Credit.
