Miscellaneous income is the last section of Less Common Income. Click on Federal on the left menu, then click on Income & Expenses at the top. From there, scroll down until you come to Miscellaneous Income, 1099-A, 1099-C and click on Edit/Add, see attached.
From that list, 2nd image attached, scroll down and click on Revisit next to any categories that have a Revisit button. The $21176 is in one of those categories. In my image below, it is Other Reportable Income.
