Retirement tax questions

I just read the IRS guidelines on self-certification and this sounds like one of the things the IRS agent I spoke to was asking me questions for. I do not think that the self-certification would work in my situation because I do not qualify for any of the reasons listed. 

 

Here is the link to the IRS page:

From my research, am I wrong in concluding that a deemed distribution for loan default would be coded L or 1L? 

 

And along the lines of the previous question, is it absolutely necessary that my 1099-R is coded M or 1M?

 

Or is it possible to still rollover the money with the 1099-R coded just 1?
