Nonprofit Formation | S-Corp election deadline missed

Quick background on my situation — any input appreciated.

S-Corp election deadline missed. I've been dealing with this for about 7 weeks now and the situation isn't improving.

I have already consulted briefly with a lawyer but the other party is not cooperating.

Has anyone been through something similar? What worked for you?

I've dealt with this before.

I ended up having everything documented, which cost about $3-6 but saved me a lot more in the long run.
