Can you go to Forms in the upper right and tell me what line the $$ amount is entered in the return, as I do not think this is an NOL.  Let me know and I can help.

Here is what the Review says, "Form 1040 Line 21, Other Income Statement 7" and it goes on to identify it as an NOL Carryforward. Then I'm asked to explain it and I'm at a loss. I agree that it's not an NOL.

I am at a loss then why it is there.  Open that "other income statement 7" in the Forms mode and then if it is not accurate, delete that Form, which is at the bottom the screen when the Form is open.

Good solution, thanks.

MichaelL1, I solved it. the NOL Carryforward was from a K1 from an estate settlement. Unfortunately, TT didn't seem to link the two together, working it backwards from 1040, Line 21. It turned out to be a legit value after I stumbled onto the source.

Great news!!  That is what is really nice when you right click you can find the source of the entry.  I am posting a very short answer so others know this is taken care and does not show as an unanswered question.  Thank you for your patience today and for using TurboTax.

When the Data Source came up initially, it was empty. As I reviewed the return prior to filing, I noticed the K1 with the exact $amount and looked at the D code on the K1; Carryover, bingo. From there, it all made sense. I then went back and manually filled in the explanation for the Line 21 Carryover.
Thanks again for your help.
