Retirement tax questions

P.S. I'm just wondering if I clicked something incorrectly within Turbo Tax to generate this extra "Explanation of Statement" form.  One wasn't automatically generated in Turbo Tax last year when I was seeking a credit on foreign taxes paid, but this year it was.  Maybe it's something new?  I don't understand when an Explanation of Statement is generated by Turbo Tax and when one isn't.

I suppose it's not a big deal to just include the form in my tax filing, so I'm mostly curious at this point.
