you didn't do something correctly in 2019. if you had the passive loss would have been allowed. in Turbotax final k-1 needed to be checked. also, you needed to enter certain disposal info in the supplemental k-1 section. this is completely separate from the reporting the sale on form 8949. sorry, but unless you extended the 2019 return, you have permanently lost the ability to claim this passive loss. without an extension an amended return needed to be filed by 4/17/2023
