"and transfer the assets from LLC"

This is very confusing to anyone trying to follow along. The title of the topic is S Corp, but it turned out there is only a C Corp formed. The future proposal was to elect S Corp. Now you are telling us there is an LLC, as Single member? You do realize every one of these entity types has specific requirements, and when you keep changing the terminology, you really are starting over with the scenario.

What you should be doing is presenting and acting on facts. Not supposition or proposals. This is mid-2022. There is the need to address 2021, which is in the rear view mirror. There is the need to address 2022 before it is too late.

You likely need to pass off all the tasks you are not familiar with.
