Losses from K-1 (ordinary business losses) don't seem to reduce taxes due to offset capital gains on stock sales (passive income)?

I have about $2k of passive losses from a K-1 LLC (Form 1065). I also have about $3k of capital gains from the sale of a stock I had held in 2019. I had entered the 2019 Cap Gains from the stock sale in TurboTax first and saw my tax return results (owe Federal but State refund, net result is I owe about $1,300). I would have thought that once I entered my K-1 losses (all of which are at risk) from the private investment that I would be able to use those passive losses to offset the capital gains tax but my return results didn't change at all. Would appreciate some guidance on how to utilize those K-1 losses against the passive income from the cap gains.

Thanks!
