you are correct on the treatment except if the property distributed was originally contributed by the partner receiving it and had a built-in gain. if so the following applies.
*box 19 code B Distribution subject to section
737. If a partner contributed section 704(c)
built-in gain property within the last 7 years
and the partnership made a distribution of
property to that partner other than the
previously contributed built-in gain property,
the partner may be required to recognize
gain under section 737. This gain is in
addition to any gain recognized under
section 731 on the distribution.
When this occurs, the partnership will
enter code B in box 19 of the contributing
partner's Schedule K-1 and attach a
statement that provides the information the
partner needs to figure the recognized gain
under section 737. The partnership is
required to provide the following information.
• The FMV of the distributed property (other
than money).
• The amount of money received in the
distribution.
• The net precontribution gain of the
partner.
