Foreign Tax Credit, No AMT, But TT Asking about Simplified Limitation Election For AMT

Saw some discussion on this, but didn't seem to see a definitive answer.

 

In previous years, I have taken a Foreign Tax Credit. However this year, after filing out this info, it is asking me about a "Simplified Limitation Election For AMT." When I look at form 6251, line 11 for AMT is zero, so it doesn't appear that AMT applies to me. If that is the case, why is TurboTax asking me this question?
