1099-R

I did a non-taxable rollover of part of my 401k account during 2021.  Although receiving a 1099-R, I forgot to load it before I filed my taxes.  The only boxes filled in on my 1099-R form are Box 1 -- Amount, and Box 7 -- Distribution Code "G".  

Given no tax implications, am I required to file an amended return or not?
