Partnerhip contribution input for appreciated, indebted property

 1) Likely as a depreciable asset, since you need to preferentially allocate book depreciation to maintain the 704(b) book basis capital accounts. Whether it appears on the balance sheet depends on the basis used to present the balance sheet.

2) At the bottom of the K-1 input screen in the 1040 package. Outside basis isn't tracked by the partnership.

3) On the balance sheet as a liability.

The Lacerte input is unremarkable. Figuring out what numbers you want to appear where (that is, developing your workpapers) is more complicated.
