Curious George would like to know who issued the 1099 NEC - The ex? - An Attorney? - The company that managed Deferred Comp? ???

Was SE tax paid on the 165K? 

Did IRS want addition SE tax on the extra $61K?

Did you get an IRS transcript to see who reported what income? 

Oh, so many questions, so few answers! It has been a problem my whole life!!!
