The posted code contains a locked candidate on 3 in box9, which also results in additional deletions.
Code after basics:

Thanks for pointing out that. It is a one step solution. The Box Line Reductions usually elude me |

I also missed the locked 3s, so I also used the UR and BUG+1. |

I might also point out that an XY-Wing (496), pivoted in r9c3, plus one transport, does the job too. |
