Free Traffic Legal Advice

I wonder if anyone could help/ advise. I received a PCN for entering & stopping in a box junction when prohibited. I was turning right onto the road from a side road (which I thought was a reason you were allowed to be in a box junction, but may have this wrong). There was no traffic coming towards me from my right, and I pulled out to turn right into the queue of traffic. I must have been in the box junction all of 20 seconds while cars to moved forwards, and didn’t hold any traffic up. Anything I can do/ grounds to appeal??

For meaningful advice we need to see the PCN so please help by having a read of

and post up here

all sides of the  PCN (only redact yr name & address - leave everything else in),
any council photos/video,(the video is the evidence),
and
a GSV link to the location.

An adjudicator will say this is a contravention but probably express sympathy on difficulty of turning right there.

Is my view.

This is what I thought, but not sure how to appeal
