I've a K-1 with amounts in box 1 & 2. When I create a second entry for this K-1 (for box 2 info), should I enter again the K-1 Part II data (Profit/loss/Cap/ liabilities)

Yes, you can enter all of that information for completeness sake, but the K-1 that will be generated is actually for your records; the information and figures are dispersed throughout your return.

Thanks

you may not know this, but most of the info in part II is not required by either TT or the IRS.  here's  what is required

taxpayer / spouse /joint

boxes in G and H 

and the at risk question under K

 

there may be items in box 20 that need to be enter for the line 2 k-1 and not on the line 1 k-1

such an item would be section 199A  - net real estate income (loss) (the qualified business income section)
