K-1 line 19 Distribution vs Return of Capital

[rodriguerex]

The K-1 form in line 19 shows, say $100. The supplemental information says that $60 of the $100 is a return of capital. Do I report $100 in line 19 and use the $60 to reduce my basis in the partnership or do I show the $60 or net $40 on the return? If I show the $60 or $40, where are they to be entered?
