Abandonment of Partnership? Form to use?

In 2024 my husband was a partner in a corp, and put $3k startup cash in during 2024. He "abandoned the partnership" in the same year by removing himself from the company. This was done formally through lawyers.  He was given $2k of the $3k startup investment back. So it would be a $1k loss on investment. He should get a schedule K-1? And report it in turbotax under investment losses, per sect 165(a)?

 

Can you please help me figure out what this would be categorized as, and where I would put it within turbotax. Thank you so much for your help! I am so stuck!
