Ahh ha! This seems to be related to foreign taxes, how to report and how to obtain a credit on your US tax return for the taxes you paid to foreign governments.
Unfortunately, I know very little about these topics, and I don't think I can help much.
Here are some notes regarding your comments.
Schedule A, is itemized deductions. You likely used the standard deduction. If so you do not have (and should not have) Schedule A.
Schedule B is a summary of Interest and Ordinary Dividends. It is determined from your 1099-INT and 1099-Div forms, and possibly other forms that report interest paid to you.
From your most recent post, it seems the 1099-DIV from Charles Schwab needs to be examined. Possibly for foreign taxes paid.
Form 1116 is for Foreign Tax Credits. See https://www.irs.gov/pub/irs-pdf/f1116.pdf and
https://www.irs.gov/publications/p514
I do not know how this is completed in turbotax.
I am copying @Critter-3 and @VolvoGirl with the hopes that one of them knows more about this situation, or can point you to someone who does.
Good luck.
