Form 982 and Insolvency Explanation

So for 2021 I had forgiven credit card debt and have completed Form 982 for insolvency.  As I'm finishing everything up when I completed the federal review and "audit risk meter", the program highlighted the form and it says, "...it is important to provide sufficient information concerning the debt cancellation with your return.  In the case of insolvency, documentation showing the insolvency calculation must be attached to the return."

 

How do I attach the documentation?  I found some general guidance online about submitting the worksheet and a brief narrative explanation of the situation, but I can't figure out how to create that in TurboTax.
