If I have $10K in short-term gains, can I sell a security with a $10K long-term loss at use that to offset the short-term gain?

See this TurboTax Tax-Tip - https://turbotax.intuit.com/tax-tips/investments-and-taxes/capital-gains-and-losses/L7GF1ouP8

Losses on your investments are first used to offset capital gains of the same type. So short-term losses are first deducted against short-term gains, and long-term losses are deducted against long-term gains. Net losses of either type can then be deducted against the other kind of gain.

the short answer is yes.  you can offset net short gains with net long term loses.
