Business & farm

In TurboTax Desktop Home and Business, I entered an IRS form 1099-B by Sales section total.  

In the Desktop version, this process requires that a printed copy of the IRS form 1099-B is mailed to the IRS after electronically filing the tax return.  

The printed IRS form 1099-B is attached to an IRS form 8453 with the last option checked.

The IRS form 8453 with option form 8949 checked.

I am able to remove the single IRS form 1099-B entry by clicking on the delete trashcan to the right of the transaction at the screen Your investment sales summary.

The IRS form 8453 now no longer has a box checked.

What was the nature of the class action lawsuit which was previously reported on IRS Schedule D?
