What is gains percentage in 1099-B/DIV from Acorns?

[bperkins91]

When I submitted my 1099-B/DIV (auto populated) and hit Next, it asked me to fill in missing info about gains percentage. I don't know what that is and there was nothing on my 1099-B/DIV relating to it.

I hit next with out selecting anything and it didn't give an error. I also tried editing it to see if it would ask the questions again and it never did.

Is that information that I need to have? Where would I find it for Acorns because the tax document did not have it.

This is what I did after I determined that the 'exclusion percentage' did not apply to my income.  See Learn more at the screen Which exclusion percentage do you see...

Then, I removed the income by clicking on the trashcan to the right of the income.  Performed a Federal Review.  Then, I downloaded the income a second time from my provider.

Since the 'exclusion' entry does not apply to my income, in TurboTax Online, I was able to remove the 'exclusion' screen by deleting the $0 entries in the boxes below the title Less common items.

Then I unselected My form has info in other boxes. 

I Continued through the software without the 'exclusion' screen coming up.
