Thank you for this post. I made an excess contribution to my Roth 401k in 2019 and had the excess distributed back to me prior to April 15 2020. My excess contribution resulted in a loss and the amount sent back to me was less than I had excess contributed. However the 1099-R I received shows the same amount in box 1 "gross distribution" and box 5 "employee contribution". The 1099-R cover letter shows the correct amounts and the loss though. How do I deduct the loss? Shouldn't they have put the full amount of my excess contribution prior to the loss in box 5?
