How can I report charitable donations from a LP's K-1 without the LP's info on the charities, donation dates, basis and value, and the charity names?

The donations were securities (non-cash), and my share (reported line 13 Code C on my K-1) was greater than $5,000. Turbotax seems to be forcing me to enter the information that I assume was on the LP's Form 8283, but which I don't have.
