Rule of 55

I took early retirement shortly after turning 55. It's been about 3 years and I'm ready to start taking some distributions from the 401K in place at the time of my retirement (and maintained since my retirement). 

 

I understand that while I am not yet 59.5 years of age, I can take the distributions from the account (again, in place with former employer at the time of my retirement at 55+) without incurring the normal 10% penalty. 

 

Can someone 1. Confirm this basic understanding and 2. Provide some guidance for what to look for to ensure that, when I file taxes for 2024, that I have all appropriate paperwork, in good order, so that the filing goes through without issues or surprises?
