So when a stock was trading at about $15 a share in Nov 2019, i sold a put option on it for strike $8 that expired January 2021. Isn't that a long term gain?

turbotax seems to be importing it from Interactive Brokers as "acquired date" on the expiration date, and "sold" date also on the expiration date.  But I didn't take any action upon it (it just expired), and I had acquired it over a year earlier.  shouldn't this get long term tax treatment?
