you may have messed up in 2021 by not indicating a full disposition on the k-1 form. that is entered in a separate section when you indicate during entry you disposed of the security. the result could be you misreported the gain or even have passive losses that have not been allowed. if you don't indicate a full disposition then suspended passive losses would have not been freed up upon complete disposition in a taxable transaction. they would still show up on the k-1 data. normally if done right the k-1 does not show up the following year. we have no way of knowing if you handled the sale correctly for schedule D and the partner income/loss
