I reported 1099 Int income from Patch of Land real estate crowdfunding. I also received a principal loss statement and I'm not sure how to report the loss. Please advise.

I invested in a crowdfunding construction loan through Patch of Land and the loan was not fully repaid. My portion of the principal loss was $342. I reported 1099-INT interest on my return and I need to know how to deduct the loss.
