I am not sure how to enter partnership sale info and k1 info

I have question about K1 - Holly energy partnership.

I sold all units so I have zero balance as of end of 2022.

 

Now when I am trying to enter info in TT premier 

I am choosing check box this is publicly traded partnership

This partnership ended in 2022.

than choosing complete disposal.

sold partnership interest

than it is asking purchase date - WHERE DO IN FIND THIS DATE AND WHAT IF I PURCHASED ON DIFFERENT DATES?

Can I leave purchase date blank and only enter sale date - I received sales schedule along with k1 - so I know sale date from that but no purchase date.

Further it ask to enter sale info 

and asking for sale price and partnership basis - what do I enter there ..?

it is asking me to enter purchase date - I received k1 from Holly and sales schedule but it does not show purchase date so how do I find it and if I can not find it - can I leave it blank?

 

 

I have the same situation form enterprise products partners
