12/3 and GFCI receptacle

[JoeS36]

Hey I been reading few different things about this shared neutral and am a little confused.

Currently being ran from panel is a 12/3 wire going to a box. In that box is the 12/3 Home run wire and 2-12/2 wires. the neutrals are all together. With a tailed neutral to a gfci outlet in that box The black off 12/3 goes to the gfci line side with that tailed neutral . in the load out on gfci is one of the 12/2 black /white going to other counter outlets.
The red on the 12/3 is tied into different 12/2 going out to the microwave recepticsl with black to the red and neutral connected together with others In box.
I’m pretty sure this is ok and up to code but before I close walls if it’s ran wrong I’d like to have someone come redo it.

Thanks in advance

How are you protecting the circuit? You’re leaving out details. What code cycle are you under? Has your inspector signed off on it?

Sounds right to me. Code requires a handle tie or a 2p breaker.

It’s existing. Im re sheet rocking and insulating walls and was looking at wiring and traced it back to basement which is unfinished

the breaker is a 20 amp 2 pole if I turn the microwave it also shuts the breaker under to the counter outlets the gfci protected ones

What I have bolded is possibly a problem. Depends if you described what you have accurately. Load side conductors of GFCI's can not tie to any non protected conductors period, that will immediately trip the GFCI when energized.
