From the instructions for 565:

"Line 27 – Withholding (Form 592-B and/or 593)
If taxes were withheld from payment to the partnership, the partnership
can either allocate the entire withholding credit to all its partners
or claim a portion (not to exceed the total tax due) and allocate the
remaining portion to all its partners. If the partnership claims any of
the amount withheld, attach Form 592‑B or Form 593, Real Estate
Withholding Tax Statement, to the front lower portion of the partnership
return. The partnership must file Forms 592 or 592-F, and Form 592-B
to allocate any remaining withholding credit to its partners. For more
information, get FTB Pub. 1017."

I assume the total tax was $800. Maybe @abctax55 knows how to allocate this withholding, as I have never done this before.
