I have errors in my 2020 federal return related to reporting of losses on covered calls that were closed out. How do I fix?

I sold an out of the money covered call on a stock and later closed out the call at a loss.  (I didn't want to dispose of the stock.) Brokerage firm reports the loss on the call transactions as negative proceeds (cost basis 0) on Form 1099 and when downloaded into Turbotax. Turbotax deems negative proceeds to be an error. How do I fix?
