Filling up form 3115... first time applying to change accounting method to MTM

Hi

 

I am filling up the form 3115 for the first time (for the year 2022) to change my accounting method to Mark to Market. Are there any guidelines on this form specifically with reference to MTM accounting? Some of the questions are bit tough to understand and I want to make sure I am doing everything right. I tried to get advise from TT live support but want to hear from members who have done this for their own MTM filing.

 

Is it correct that this form needs to be filed only once, for the first year of changing the accounting method? 

Thanks
