the sale gain should already be on the k-1 lines 9a 9c and maybe line 10. to enter the sale info in the disposal section would then result in you double reporting the gain on sale.
in the disposal section the only thing that should be reflected is any gain or loss on the termination of the partnership. to do this you need to know your tax basis.
if the k-1 is marked final your ending capital in part II section L would normally be zero.
]f not then it's likely the partnership retained some of the sales proceeds to cover contingencies in which case you don't complete the disposal section this year.
The following is a generalization since there is no access to your k-1.
if the k-1 was done according to the iRS instructions Part II Section L
Beginning Capital Account normally should be your tax basis at the beginning of the year (there can be exceptions to this)
Current Year Net Income (Loss) should be the net of the various income and expense lines in Part III (FYI 9a includes 9c)
Other Increases (Decreases) normally would be zero
Withdrawals and Distributions should normally match 19a. It's unlikely there is anything for 19b or c.
the net of these is your ending tax basis which if it's a final K-1 should be zero the same as shown for Ending Capital.
so if it's a final K-1 and tax basis is zero then in the disposal section you enter zero for sales price and zero for cost. this should result in the k-1 not rolling over in 2023 and any suspended passive losses being allowed.
If the partnership sold property in a state with a personal income tax and you are a non-resident of that state, some of the money indicated as a distribution (19a) might actually be state income tax withholding. this should be shown on the k-1 for that state.
