How to Report Loss on Excess 401k Contribution

I mistakenly over contributed to my 401k due to multiple employers.  I recognized this mistake, had the excess contribution returned, and know how to report this excess contribution on my tax return for the year thanks to this forum.  What I was hoping someone can help with is how to report the loss attributed to excess contribution.  My excess contribution was returned minus the loss while invested in the plan.  Can I report this loss as a negative amount on the “other income” line of my tax return or is there another way to report the loss?

 
Thanks in advance for your help.
